Just read the Thurston Moore biography, and been on a major Sonic Youth kick the last few days. I think my top 5 favorites are EVOL, Daydream Nation, Sister, Murray Street, and possibly either Goo or Rather Ripped. Tough call though. But EVOL and Daydream Nation constantly battle it out for my favorite. "Shadow of a Doubt", "Starpower" and "Green Light" are the songs that I'm obsessed with on EVOL, and "Candle", "The Wonder" and "Eric's Trip" still take my breath away.
