RATS is a desktop app for DJs with large, poorly-tagged libraries. It listens to every track on your own machine, labels genre, mood, instruments, and vocals, and proposes tags from what your library contains. Discovery searches about 18 million Beatport and Bandcamp tracks by sound, starting from a track, tag, or set you own. Tags and sets sync into Rekordbox, Serato, Engine DJ, and Lexicon. One $50 purchase for macOS and Windows, with a 14-day free trial.
