Song suggestions

Hello!

Was wondering if some people would give some suggestions of upbeat songs to use while working out? Ive been going about a month now just using an elliptical machine and have lost 13lbs so far.

Main reason doing it is to lose some weight before pregnancy, help me with my hyper side effect of medicine and it's helped prevent me from some negative things I used to do when stressed out. am getting kinda bored with what I have. Up for any suggestions! As of right now I have lots of P!nk, Lady Gaga ( love poker face!), Eminem, and a few odds and ends.

Thanks!!
