The Presidents of The United States of America - Lump
Also known as PUSA, these guys are just a fun band that got started in 1995 and ever since I first listened to them I find myself going back every few years and listening to a few of their songs. Did you know they performed at Nintendo World in 2011 for a Pokemon launch event? They even sang a tribute song called "Can't Stop (Catchin' Em All)". They have also released a new album this year. I'll have to take a listen to it in the near future. In the mean time why don't you listen to "Lump".
