If you like mixes (I know I do) you should really listen to this guy: http://www.youtube.com/channel/UC5nJj-L4swL90huglMhKgOg
He makes amazing mixes, I can point you to some of his best if you want.
Personal I'm more of a Chillwave, DeepHouse, Drum n Bass listener. So if you want some tunes of that, give me a shout.
Here are some great channels anyway:
