Interesting remix, good work!
For the record, I'm not a huge fan of this song. That said, it has that quality where you can tell millions will like it, even if you don't. I liked your take on it, especially the "hello" parts. After that, some of the lead vocal seemed out of synch, but maybe you meant that and it's not a huge deal.
Overall, you made the song more listenable, to me, who wasn't a fan of the original. This mix should be played in the Hard Rock Cafe or similar, after they've just dimmed the lights...
