Yesterday, I downloaded a new album on iTunes. When I tried to use SoundHound to view the lyrics, it wasn't working for some of the songs. I checked the files on my Mac and to my big surprise, the extensions of those songs are .M4P. The DRM aren't back, but having M4P files is seriously annoying because of compatibility issues. Anyone else? Is it a problem with iTunes 11? I contacted customer support and I'm suppose to have an answer in the next 2 days.
