I like both of these groups quite a lot - - Weezer and Toto.
Weezer has a big hit currently with a cover of Toto's song "Africa." Yet, I don't really like Weezer's version because, to me, it sounds almost note-for-note the same as Toto's original. If all a group does with a cover is to make me immediately think of only the original and how much I like the original -- then don't bother making a cover. I'd rather just hear the original.
