Full disclosure: I just got my Smiths Complete boxset this week, so I've been listening to a LOT of Smiths music lately. Don't hate, I only bought the 8 disc set, not the deluxe version.
At any rate, the fine folks at NME have put together quite a massive feature on The Smiths! They've compiled a list of Morrissey's most memorable quotes, the top 10 Smiths b-sides, and they've asked some pretty cool musicians like Noel Gallagher, Alex Kapranos, Ian Brown, Ben Gibbard, Peter Buck, Ryan Adams, and more to reveal their favorite Smiths song. Oh, and there's even a Smiths limited edition magazine you can purchase (yes, you can order it in the U.S. It comes to exactly $17.99, if you're interested.)
Finally, take the NME poll and let them know your favorite Smiths track, or just be a lurker and check out the poll results so far.
