Ke$ha - TiK ToK.
The bass/synth that comes in in the chorus is huge. Does anyone have an idea how to make it sound so... sharp? ...if you know what I mean

Sure it starts off with a saw wave.. but, what's next? Maybe it is just made with a good hardware synthesizer?
EDIT: Can't link a youtube vid since I'm at work, but it drops at 0:32 on my shitty 128kbs mp3. Maybe the official video has an intro or something, but sure you'll know what sound I mean

EDIT2: Typo... the song is actually called TiK ToK and not Tic Toc, hooray for 2010 pop music.
