I recently purchased "Time Out" by the Dave Brubeck Quartet (jazz). Its full of cool, catchy compositions in loads of different time signatures. Also, whenever I feel burnt out, i tend to listen to things that i enjoyed when i was younger. One such band is silverchair, who happen to have a pretty catchy new album as well.
Dog Fashion Disco - 9 to 5 at the morgue (odd, but interesting) Tribal Disco noise - Conceited (groovy!) Finger Eleven - Sick of it all (LOVE this song!) FeFe Dobson - Take me away (What?!)
