🎵 This looks like an interesting music app…KORD Multitrack Music Player - apps.apple.com

KORD is the first subscription-based service to offer access to stems - the building blocks of songs. KORD’s patented interactive music player empowers listeners to deconstruct landmark songs and discover how they were built, track by track. All stems featured in KORD are licensed from the original multi-track master recordings, enabling subscribers to hear the music exactly as it was recorded in the studio.
