We all have those 100+ song playlists that we listen to by hitting the Shuffle Play button. Somehow it never truly feels like a 'mix' ... but just a random jumble of songs that sometimes abruptly stop and start after one another.
This experience can be made better if crossfade was automatically toggled ON whenever Shuffle Play is active. Both of these functions already exist in the app (Shuffle Play button at the top of the playlist view in the mobile app, and Crossfade buried in the Settings menu under Playback). Just make it toggle crossfade to ON whenever this button is hit, then toggled back to OFF when you start playback anywhere else outside of Shuffle Play.
Everybody support this idea so we can enjoy perfect playback of our meticulously created party mixes.
