Also, though it's way overplayed at this point, here's a good example of why the theme song to Friends was so effectively well done. One night, before I had ever even seen ONE episode of Friends (this was probably 95 or 96), I was driving home and heard this song on the radio. "I'll Be There For You". I thought to myself "Damn, this sounds like something you'd hear as theme music for a sitcom". Again, I had never seen an episode of Friends, EVER. I had absolutely no idea that this WAS, in fact, the Friends theme song. It just sounded like sitcom theme music to me.
