Half your tracks have no key, or a key you do not trust. The genre is blank on some and wrong on others. The same song is in the collection twice, and a few files moved when you reorganized a drive.
Fixing that by hand, one track at a time, is a weekend. Most DJs do not, and then dig through the wrong tracks at the gig.
Pick a playlist, a Collection, your selection or the whole library and choose Match. CuePoint looks each track up on Beatport and keeps every candidate it found, with a score and the reason it turned down the ones it did not pick.
It accepts a match on its own only when the best candidate scores 95 or more and passes every check. Everything else waits for you in the review queue, where the keyboard does the work: A accepts, R rejects, N moves on.
An accepted match gives the track Beatport's key. Its tempo, genre, label and year are offered next to each other, and you tick the ones you want to apply. Your own values go on top and Rekordbox's stay underneath, so any change can be taken back.
Title, artist, remixer and album are never changed.
Clean groups tracks that may be the same recording: the same file, the same Beatport track, or the same artist, title and mix. It also lists the files that are missing or unreadable, and reports a drive that is not plugged in once, not as thousands of missing files.
A Health tab counts everything that needs you, and each count opens the Library on exactly those tracks.
