I've got it. I'd say it's worth buying, partly because it's quite funny in places (where they can't pronounce the words yet still put everything into it) and at the same time a lot of the arrangements are actually very good/different.

I've got the album. I'm sometimes confused by what the bands are doing, and sometimes have to wonder exactly what song it is they're covering, but I really like how the disc shows you just how far their influence has reached over the years.
