Well, I set it to 2 and my slug stopped responding.
I even gave it a whole day to scan, but I eventuelly had to reboot.
So, are there any tag-fixing tools so I could adjust those files on / from my PC?
You can do it from iTunes, by telling it to remove tags.
You could also try this http://www.mp3tag.de/en/index.html.
But I’d like to see the bad files. You could email it to me at ron at pedde.com.
