This makes me consider learning guitar again, which I failed at miserably: http://www.youtube.com/watch?v=q3WIs6j7g4w&feature=related And I actually enjoy Nyan Cat. It's amusing, and good background music.
as I was watching the 10 hr one. I heard it freeze for less than a second. I went back to that point and I found that ever 5min 33sec. is when the song loops itself. useless info, but whatever.
