This is the best crossfading app Ive heard for your own music on your iPhone. The crossfade is VERY smooth, and seems to work better than most.
A couple of complaints about it though. Its missing a couple of key features, the most notable of which is the lack of integration into the standard iOS media controls. The lock screen doesnt show what youre listening to, and while using this app, any built in media controls continue to control the default iOS music player, which tends to play the music on top of the media mix pro.
Integrated headphone controls also dont work with this app.
But, given that this app is something of a one of a kind app when it comes to crossfading music, and given that so far it seems stable and reliable, Id suggest it to anyone willing to give up those couple of key features. That being said, Id easily give this app 5 stars of that feature was added.
