Thank you, Mike! The solution for me was just `emms-cache-reset'. See below.
Kind regards,

Well, I did not get any messages. Apparently every file on my disk was cached
as playlist. I think I just called `emms-add-playlist-directory-tree' on a
whole disk at some point by mistake instead of `emms-add-directory-tree'.
Everything is playing now after I `M-x emms-cache-reset'. La-la!
