If you're a big Pixies fan, you'll like it because it's got everything you like in a Pixies song. If you're a goddamned faggot piece of shit with zero taste in music, you'll be Schmoopy. http://www.rollingstone.com/music/videos/pixies-release-bagboy-first-new-song-in-nine-years-20130628
It's the only time she's "quit". Previous to this, it was the band calling it quits. This time it's just her leaving, and my understanding is they're going to replace her. She's on this song, though, and they may have recorded more.
Do not like. Most bands blow their wad by their early 30s and can't write any more hits or good songs.
