I really like SHTYM actually.... really fun/quirky indiepop. Most all of their better songs you can hear here fyi -

As for Poop Yer Pants - is more or less the same kinda indiepop - tho a bit more mainstream... they sent me their cd and T-shirt for my station. Not quite sure what to do with the T to be honest - lol...
