I just got back from New York and find myself happily faced with an iPod shuffle and a $40 iTunes gift certificate. I am working on uploading all of the albums I own (I am in a major CD buying phase after an 8 year hiatus). Here's what I need from you : 40 songs that you think are worth buying from iTunes. This means a song that makes you (you personally and hopefully me) want to listen over and over again. Make me hip. Make me smile. Make me dance. Make me cry. Make me sing. Make me get in the mood for love.

I will take album suggestions as well. Many thanks in advance.
