YouTube as a Music Player?

Just want to write a quick post about music, more out of curiosity than anything else! Lately I've found myself using YouTube as a music player more than listening to the MP3's on my computer. The only thing that used to put me off YouTube for music was the sound quality, but with the high quality options now available, it's perfect for sound.

What do you use for music? YouTube? iTunes?Let me know with comment below.
