Basically as the thread title says! I have a playlist on youtube as I'm always without my PC/harddrive/MP3 player and am in the process of putting a few tunes I like on but need something new!
So far it has some Jason Mraz, Pink, Taylor Swift, Daughtry, Paramore, Chris Cagle, Keith Urban, Gym Class Heroes, Mcfly (One song! Honest! 
) and Owl City. I have a wide selection of things I do listen too though, so recommend me some more please :)
