Last week when I searched for a song I would get tons of results with m4as. This week searching for the same songs all day and all weekend I cant even get one. This has been the case since the weekend (when there usually are a lot more users therefore a lot more m4as). I don' think this is just coincidence like a lot of people with m4a files are not available because I've searched some pretty mainstream stuff on there and hardly anything.Can someone help me with this problem?
