Ok that is awesome. I do wonder though. If you can use any music you want, I wonder if that would draw the ire of the music companies. I know Sony is a music company and it would be funny if they flag videos with their music, but I was thinking more about other groups. I know how bad it is on youtube. The twitter comment does say 'original' music, which could mean only music you actually make is acceptable, but we will see.
Plus, if they are going so far as to allow you to use mp3s that are stored on a usb drive, then why in the heck are they not offer an app that can play local media? The Music Unlimited app could be updated to do it (even if I have had a pretty poor time with it up to this point). I would be grateful to them if that turned out to be part of the plan for this next update. I would also appreciate it if it supported mp3 and flac files since most of my ripped music is in flac.
