Mixing (or at least crossfading) on the iPod Touch/iPhone

[publicradio]

Hello,

I'm wondering if anyone knows of a good app for mixing playlists. Ever since the newest iPhone OS (4) you can create multiple new playlists on your device. From this point forward I'm going nuts making mixes for friends, for my podcast et cetera.

However, It would be nice if there was a way to program blends and things from the device. If there was a proper DJ app to beatmatch records and program mixes, that would be cool. Really though, what I want more than anything is just to be able to control the timing of the next record and crossfade the ends in some places.

Then I would like to be able to get this mix from the device onto a CD or onto my computer. Does anyone know of a good app that would accomplish this?

Thanks.
