I find I really like Amanda Palmer's UkuleleHead
album. Maybe she's not the world's best vocalist, but she's good, and she's a very honest and fearless performer, and I like that. Also, ukulele!
It can be downloaded for the princely sum of 84cents here: http://music.amandapalmer.net/album/amanda-palmer-performs-the-popular-hits-of-radiohead-on-her-magical-ukulele
Or you can just listen to it and not download it. But really, even I can afford 84cents.
