I don't tend to have all-time favorite singers. There are just too many people who are just too good. However, I do tend to have "favorite for now" singers; people who I will listen to while excluding all others.
Hania Lee has reached that point. She's a neat Australian singer with a flair for absurdist songs. I am a sucker for absurdist songs, especially false-cheery absurdism. (Think "Always Look On The Bright Side of Life" as sung by crucifixion victims.)
Here is "Relax and Smile"
Update: I was trying to make this into a player, but the stupid thing downloads every time I hit the post. You get to click on it instead. Sorry.
