Another “meh” year, IMO. Guess I’ll go for Gorillaz, but I really don’t care.
Well, I guess after 2004’s bumper crop of decent #1s, there was no way to go except down. Still, Beck’s “E-pro” good enough to get my nod here.
Also-rans of 2005 from Playlist Research
From the list of also-rans, I’m going with…Beck again, “Girl” (cool song, and double-plus good fun video of L.A. Hispanic culture meets Mad Fold-ins…) 
As always, some of my favorite alternative songs of '05 that didn’t make the list:
Metric - Monster Hospital
Acid House Kings - Do What You Wanna Do
Portastatic - Through With People
The New Pornographers - Use It
The Clientele - E.M.P.T.Y.
Art Brut - Good Weekend
The Dirtbombs - The Sharpest Claws
Of Montreal - I Was Never Young
Sleater-Kinney - Jumpers
Went with Green Day since I never voted for them.
Went with Gorillaz - I like a lot of what I have heard. Damon Albarn does interesting stuff…
Beck for me.
