Ok, to whet your appetites for updates, in the absence of results, here are few teaser opinions.
A couple of the albums have one song I've heard before, which I liked. On one of those albums, none of the other songs interest me as much, which is a bit disappointing. The other is a more enjoyable album than I expected based on the song I'd heard before.
One of the other bands I was sure I'd heard a whole album by before, but apparently I haven't, which is extremely confusing. Anyway, it's very good.
One of the albums I'm enjoying at least as much as the winner from the last round... maybe even slightly more, haven't decided yet.
