My main complaint is that for me is starts leaking memory when I try
to add that many songs at once, eventually using up all system
resources, and getting killed by the OOM killer. Happens 2/3 times.
That is a bug, not normal behavior. I'll file a bugzilla some day
when I get sufficiently annoyed.
Its been fixed I believe in the devel version, unfortunately there has
been no 0.9 release yet so it a go and get a copy out of arch fix.
