YouTube is definitely my first stop when I want to check out some new-to-me music that my friends have been raving about. It's my new, on-demand version of MTV.

I dislike what often happens if I add something to a playlist for future listening, however -- videos disappear, for a multitude of reasons. I have several genre-specific playlists I've curated that require regular maintenance because of this, and I can't always find alternatives for stuff that's gone offline. It's frustrating.
