120 tracks,
every one clearable.
Scored from a real library, cut to the beat, and levelled to -14.0 LUFS with -1.5 dBTP of headroom — the level the feeds normalise to, so nothing you post is turned down on arrival.
The library is measured, not tagged by hand: every track carries its tempo, its energy and its licence, so the engine can pick one that fits the cut instead of one that fits a mood word. 22 hours of music in total, from 62 to 185 BPM.

119 of the 120 require a credit. When one is used, the credit travels on the job and is appended to the caption we hand you for posting, written out in full — because a licence you cannot comply with is not a licence you can post under. If you post the file somewhere else yourself, that line is the one to carry with it.
Levelling, and why it is done last
Whatever re-encodes last owns the level. Music, voice and the original audio are mixed, then the finished file — not its parts — is measured and brought to -14.0 LUFS with -1.5 dBTP spare, which is the headroom AAC needs so the peaks survive the platform's own encode.
