Rediscover the music you already own. Move through forgotten tracks with adjustable Medley playback and a non-repeating shuffle. Rediscover your music with Medley playback. RE:TR4CKS is an offline music player that plays selected portions of your tracks one after another, helping you quickly rediscover forgotten music already in your library. Old favorites. Deep cuts from albums you used to love. Tracks you forgot were even in your library. Even with a large music collection, it's easy to end up listening to the same familiar songs again and again. With Medley mode, you choose where playback starts and how long each track plays. RE:TR4CKS then moves through your shuffled music automatically, letting you revisit more of your collection in less time. When something catches your attention, switch to normal playback and enjoy the full song. RE:TR4CKS isn't about finding new music. It's about rediscovering the music you already have.
