I am a die-hard metal head whose never listened to anything without a guitar in many years. And a few days ago I discovered Caravan Palace. I'd embed music video but it isn't safe for work so here's a link instead: watch?v=UbQgXeY_zi4 Now I can't stop listening to electro-swing music. Too bad it is a bit of a niche genre - not many bands/songs. Other than that, Korpiklaani's Lempo is a pretty solid favorite I keep returning to.
I heard that if you make it through the entire It's Everyday Bro song, Target will give you a discount on bleach.
