songs. Radiohead is a group I have heard of from a million people, including some whose musical tastes I like. I can't think of a single song from Radiohead that I know.
On the flip side, sometimes I stumble on to some obscure band and wonder why they either never made it big or why it took me so long. Eyes Lips Eyes is an example of a band I wonder why they never made it big. I recently stumbled onto a song called The General by Dispatch. I had never heard of Dispatch. The song came out in 1997. Dispatch is somewhat obscure, but it seems like they have made a nice living for themselves doing music from what I can tell.
