Playing catalog albums needs an Apple Music subscription. Your listening stays on this device; there is no account to create. BEATSY PRO Beatsy is free to download and play, and pause, skip and changing discs stay free. Without Pro, a short Pro introduction appears over the player after about 10 seconds of each disc and again after every third finished track; the music keeps playing and the introduction can be closed after a few seconds. One lifetime purchase unlocks all machine finishes, silver discs, the track list, the sleep timer and landscape mode, and the introduction no longer appears. No recurring subscription or free trial. Payment is charged to your Apple Account at confirmation; restore with the same Apple Account. Apple Music catalog playback requires a separate Apple Music subscription.
