Hehe
You Turned one of last year's best hits into an amazing, very-danceable song. Congrats.
You kept the same melody but with the saw instrument, made much better than the discordant, bubbly instrument in the main song. The vocals were awesome, the effects you added to it were amazing, The reverb made sound trance-like but at the same time it was very upbeat. The only thing I didn't like was that the vocals start loud, then all of a sudden the become lower, and than back to loud after a bit.
Loved it though, Instruments were good, non-repetetive and interesting.
Drums rocked, they were generic but it's hard to make a unique drum beat on a remix.
*Overall*
Good, interesting, work on that vocal problem cuz it became annoying.
