Seems there is a bug when ripping an unknown CD (unknown to the CDDB that is) after having ripped a known one. The files seem to be named after the tracks on the last known CD.
I rip "Jimi Hendrix - The Ulitimate Experience"
and then I rip "LadyLinn and her Magnificent Seven" (unknown by CDDB, as it's a demo) and the files in that folder are named after Jimi's songs.
I guess there's an array not emptied/reset.
I know, this is a minor bug, but it's a bug! ;)
