MTP mismatch...m230

Okay, so I was listening to my mp3 than turned it off, turned it back on 3 minutes later and than it said MTP DB mismatch Format, not enough space for music DB please free 8 mb. When I hooked it onto the computer all the songs were there so I deleted approx. 16mb, but nothing worked, so does anyone now what i need to do? Also, it can’t be formatted. When I try to delete songs it won’t let me, if I select more than 5 songs to delete it wouldn’t do anything.
