I can get my modules (mod, s3m, XM) playing fine in amarok but it won't add them to the collection. I get the following error "The following file could not be organized: /home/..../file.mod" when trying to copy or move to collection. I am using xine engine. Does anybody have a clue how to solve this? 

That won't work, since TagLib doesn't have plugins for reading module tags. And then, there's so many module variants, it would be quite a task writing tagging plugins for them.

Well then there is one thing where winamp and foobar2000 did better but I'm not switching back.
