The best app for crossfading – My DJ - Crossfade for iPhone Review

Just know that every time you touch Songs , you’re resetting your queue playlist and it will go to shuffle. This is the only app I’ve found that will crossfade into the next song when you fast forward and that you can adjust the crossfade length (although that feature was lost in last iOS update and I’m sure will be addressed.)
