I'm a young guy, so mine are much more.... Young. LOL
Recently, I've really liked the songs by Fun. but I wouldn't say they are my favorites.
I also have liked rap in the past, although I don't listen to it now. I loved Tedashii and Trip Lee (they are Christian rappers).
Classic rock has always been good too. I grew up listening to some of my dad's albums, so I really liked Bob Seger's "Old Time Rock'n'Roll." Also, more my time, was Michael Jackson, and he was a creep, but he was amazing. I loved "Man in the Mirror" and "Black or White."
I'd probably say right now, I'm really into the mellow, laid back sound of John Mayer and (especially) Jack Johnson. His music is just so easy on the ears and well written, I am always impressed.
