So I'm a pretty big music fan but want to expand my musical horizons. I'm pretty much a fan of anything. What are 5 songs that are must haves? And not songs that will be all done and played out in 6 months. That also means they don't have to be classics. They can be any genre, I'm not picky. (And you don't have to limit to 5 songs.) Just want to see what other people like.
