What Happens Between Upload and Approval: A Breakdown of Fast Review Times

Between the moment you click upload and the moment your cover song goes live, a distributor runs a specific sequence of automated and human checks: file integrity, metadata validation, artwork compliance, and — for covers specifically — a licensing and songwriter-credit check. Understanding this sequence explains why some releases clear in a few hours while others sit in a queue for days, and it gives you concrete levers to pull if you want your release reviewed faster.

Moderation is not a black box. It’s a checklist, and most delays trace back to the same handful of predictable failure points rather than random luck.

What actually happens during moderation?

Moderation is the process a distributor runs to confirm a release is technically sound, correctly labeled, and legally clear before it’s sent to streaming platforms. It typically happens in four stages, and understanding each one tells you exactly where a submission can stall.

Stage 1: Automated file and audio checks

The first pass is machine-driven and fast, usually completed within minutes. The system checks that the audio file meets format and bitrate requirements, that there’s no clipping or silence where there shouldn’t be, and that the track length and file structure match what platforms expect. This stage rarely causes delays unless the file itself is corrupted or in an unsupported format.

Stage 2: Metadata and artwork validation

Next, the system cross-checks your metadata: artist name, track title, release date, genre tags, and artwork dimensions and content. Artwork gets rejected more often than people expect — text that’s too small, watermarks, blurry resolution, or artwork that includes streaming platform logos are all common triggers. This stage is also automated in most cases, but flagged inconsistencies get kicked to a human reviewer.

Stage 3: Cover song licensing verification

This is the stage unique to cover releases. The distributor needs to confirm the original song is eligible for a mechanical license — meaning it’s a legitimate composition with identifiable songwriters, not a parody, mashup, or unauthorized derivative that falls outside standard compulsory licensing rules. For a distributor with automatic mechanical licensing built into the upload flow, this check happens as part of the same submission process rather than as a separate manual application, which is the main reason cover song review can move as fast as it does.

Stage 4: Final human review and platform delivery

A human moderator does a final pass on anything the automated system flagged, then the release is packaged and sent to each of the requested platforms. From there, individual platforms like Spotify or Apple Music run their own final checks, which is a separate timeline the distributor doesn’t fully control.

Why do cover songs take longer to review than original songs?

Cover songs require an extra verification layer that original compositions don’t: confirming the underlying song is licensable and that songwriter credits are correctly attributed to the original writers, not the performing artist. An original song only needs to clear technical and metadata checks. A cover needs those same checks plus confirmation that the composition itself is a real, identifiable work eligible for a mechanical license — a step that doesn’t exist for original material at all.

This is precisely why distributors that bolt on manual licensing request forms for covers tend to be slower than ones that automate the check. If a human has to manually look up the composition, verify publishing information, and file a license request as a separate step, that’s hours or days added to the timeline before the release even reaches audio review. When licensing verification is built into the same automated pipeline as the rest of the upload, the cover-specific step adds minutes, not days.

What causes most moderation delays?

The large majority of review delays come from a small set of avoidable errors rather than backlog or bad luck.

Missing or mismatched songwriter credit. Cover releases need the original songwriter listed in the composition credit field, not the artist performing the cover. Leaving this blank or crediting yourself is the single most common cause of a hold.
Ambiguous song identification. If the title doesn’t clearly match a known, registered composition, the system can’t verify licensing eligibility automatically, and it gets kicked to manual review.
Artwork policy violations. Platform logos, blurry images, or text-heavy graphics almost always trigger a rejection and a resubmission cycle.
Non-eligible source material. Parodies, unauthorized mashups, or songs with unclear ownership can’t be cleared through standard mechanical licensing and will be rejected outright rather than delayed.

Each of these is fixable before you submit, which means most delays are within the artist’s control, not the distributor’s.

How fast is fast, in practical terms?

On a distributor built for cover songs specifically, with licensing checks automated into the upload flow, review commonly completes within a day when metadata and credits are submitted correctly. That’s the benchmark worth measuring against, since it directly affects whether you can realistically capitalize on a trending sound or a timely release window. A cover of a song that’s spiking in popularity loses much of its commercial value if it takes a week or more to clear moderation and reach platforms — by then the trend has often moved on.

This is one area where the cost of a distributor and the speed of a distributor tend to be connected. Services charging annual fees or per-cover licensing surcharges, like TuneCore’s base $24.99/year plan plus separate per-cover fees, often route each cover through a distinct manual licensing request rather than an automated check, which adds processing time on top of added cost. A distributor charging $1 per single with licensing built into the same pipeline as the rest of the release isn’t just cheaper — the automation that keeps the price low is often the same automation that keeps review fast.

What can you do to avoid a slow review?

Submit clean, complete data the first time. Fill in the original songwriter’s name accurately, use the exact recognized title of the composition, upload artwork that meets standard resolution and content guidelines, and double-check that your file format matches the platform’s requirements before you upload. None of this guarantees instant approval, but it removes the friction points that push a release into manual queue territory in the first place.

It’s also worth remembering that moderation speed and payout structure are connected in a practical sense: a distributor with no annual fee and payouts starting from $10 only benefits you if your release actually gets to platforms while it’s still commercially relevant. Fast, accurate submission is what makes the rest of the low-cost model worth using.
