let me borrow his Wolfmother CD, so I can now give an informed opinion about Wolfmother:
I think they're alright. Nothing special, but the songs are very catchy. Catchy to the point where I'm almost sure I've heard them before, which leads me to believe they're all stolen from some band I know better.
I don't see the comparisons to Pink Floyd and Zeppelin at all, really, but I definitely see the similarites between them and Black Sabbath. I pretty much think of Wolfmother as a poppier Black Sabbath.
Anyhow, I will admit that I have rocked out to pretty much every song on the album, and I'm only just starting the second listen. Although I don't think the album is anything extraordinary, I will probably end up buying it nonetheless.
The only thing I really don't like about Wolfmother are the lyrics. That half-assed mysticism-and-girls crap should have died before it started.
