Reinstalling ogg-support got me back to where I was. Should have thought of that myself, thank you. I've installed decoders-support, but get the same result. One odd thing now is that one album has appeared in the list of albums for one particular artist, and the list says it has 3 songs (which it does, it's an EP), but when I go in it says there's one song, no details for it. I'll have some time later to try again. Thanks for the help so far.
