The tricky part in voting here is that there are a number of *classic* alternative tunes that are present on albums that simply aren't strong enough to get my vote. Do keep in mind that I absolutely HATE the music of Green Day, Tool, and a few other bands, so I simply could never vote for them.
Also, I find it hard to believe that they wouldn't give you the option of voting for New Order's Power, Lies and Corruption. That was a BREAKTHROUGH alternative album, featuring that wonderful hit "Blue Monday." Plus, I also think that Moby's Everything is Wrong album could have at least made the list of potential albums, along with Death Cab For Cutie's Transatlantacism, The Cure's Wish album. I may not have voted for any of those, but they probably deserved to make the list. Do note my write-in vote for Yaz (Yazoo) and their album Upstairs at Eric's. That is an EXCELLENT work of early 80's Brit-pop.
And yes, maybe I should've voted for Happy Mondays, Jane's Addiction, David Bowie, Elvis Costello, and a couple of others, but you have to go with the music you know best in voting.
