Actually you have to register and sign in to vote. So unless you plan to construct a sockpuppet identity--not recommended--you can't do often. I refer, of course, to the AV Club's Undercover competition. There have been some nice, off the cuff cover songs included, worth checking out whether or not you plan to vote.
Here's one that I had to put near the top. It's Baltimore's Wye Oak, paying tribute to the songwriting genius of Dave Davies. Yes, Dave. (And since Anheuser-Busch isn't giving me anything, I'm well within my rights to tell you you can hit pause before the beer commercial.)

May do Saturday Random Ten. Will help if Earl's sloppy seconds have really ended the heat wave.
