I almost never write reviews, but this app is great. I want to thank the developer for making this. I was able to make a mix for a three-hour dinner by importing an iTunes playlist, adjusting what percentage of each song I wanted to play (in my case, 95 or 100%), and then setting the crossfade time. This app saved me from having to make a "real" mix of dozens of songs by hand.
