Two reviews one post....ladies...
I'd probably give both a 6.. There were parts of both that I didn't care for at all, but I came away from both enjoying them. For Black Sabbath parts of songs were kinda bad and I didn't care for the guitar sound they had going on, but overall I enjoyed it and came away satisfied.
I have more to say on Underclass Hero because I literally just finished listening to it. I didn't much care for the first few songs. They felt too pop and not enough punk for me. I kinda felt like I was listening to some inoffensive generic pop punk radio song (despite the like one use of certain f words that are censored on the forums, although it was used in an immature context) that felt like something you'd expect to hear in the background from a teen/young adult comedy movie circa 1999-2003-ish, hell I heard In Too Deep on early Malcolm in the Middle, but once it got to Count Your Last Blessings, my favorite song on the album, I felt it picked up. About halfway they tried to do a slow song that I didn't care for either and it was either that one or another one that reminded me of Hate Me by Blue October. The rest of the songs from then on for the most part I felt were better. Now that I relisten to them I like the first song more, but I still feel the album overall is pretty derivative and on the generic side, but executed pretty well. The lyrics were nothing special, but at least they didn't feel as excessively immature/adolescent/whatever as other pop punk I've heard tends to be. This album and the like two Sum 41 songs I've heard before may not be terribly original, challenging, emotional, skillfully played,etc, but I had fun and there's nothing wrong with some simple fun.
