Update: Due to lack of free time, I haven't been in a position to re-check the release dates of nominated tracks myself, so now we have encountered a problem. Apparently, May's TOTM winner track, Harmonic Rush - Head Rush, was released on June 2nd, not in May, so we have to disqualify it from this poll so the winner for May's TOTM track is the runner-up:
Menno de Jong, Stereojackers vs. Mark Loverush & Shelley Harland - Connected (Luke Terry Remix)
I'm sorry for the inconvenience, fellow TPers. I will try not to let this happen again.
