MixDJ - DJ Software for Phone

You can do beatmatched, gapless, cross-faded mixes of your songs, and then apparently save the mixes to share with your friends. You can’t unfortuantely download the app, as NXP are known for doing handset preloads instead - but you CAN take a look at their website, www.software.nxp.com, for more info. Maybe we’ll see a download version coming at the some point, which would be cool indeed!
