Fun music suggestions? My tracklist is busted.

Not to say I don't like the music I listen to, I'm just so sick of hearing the same ****, lol, it's deflating my motivation. So I was hoping you guys could help me out a bit.

I really like pop and R&B the most, but I listen to all kinds of things including orchestrated compositions. My favorite artist is Michael Jackson and I tend to dig things that are funky/disco-y and high tempo with a strong melody, but I like mid tempo stuff too. I enjoy both old and new school and I'm open to various genres/languages (I have favorite songs in Spanish, Japanese, Portuguese, Korean, Russian, French, Hindi and more) and love exploring new and unique music, so please, what are some suggestions or your own favorite workout tunes?

Just don't give me anything too corny and played out like "Eye of the Tiger", please, lol. I'm also pretty vehemently against dubstep but if you think something's awesome then hell, I'll give it a shot.

Thanks. ^_^
