It was a lot easier than I thought: With a single click, I changed the Warp Mode from Beats (the default option) to Re-Pitch for all tracks except "There Is A Party", which I set to Complex warping because Senor BoBo sounded much too squeaky, instead of boyishly cheesy.
Btw, I find your assessment that Complex mode makes a track sound "digital" and soft very appropriate. But then, Eurodance MP3s aren't exactly the most valuable source material to begin with...
Thanks again for the explanations and pointing me in the right direction, KoS! Would you mind giving it another listen?
