Listen to the demo with beatsbydre headphones (if u have them) and u'll get addicted to the song even more, the instrumental is not really clear in the demo and her voice is a bit higher than the instrumental, but whatever, that doesn't make the song any less amazing and we're still gonna hear the final version, so the song is pure epicness!
why beats by dre? i have jvc xtreme explosives which are 4 times cheaper then the tours that i had originally bought and slay harder lows (bass) and overall, better comfort. anywho. yeah sounds hot.
this song is hot.. the definition of hot.. didnt sound desperate and Guetta-y.
ommggggggggggggggggggggggggggggggggggggggggggggg@@ @@!!!!!WASFAFAFAFAFAFADADDFAFA#ERQ#R!!!!!!!!!!!!! so fuccccccccking gooooooooooooddd! back to 1999 christina
For a demo this is pretty tightly made. If it's changed, it will become faster and actually kill off some of the instant likeability of the song.
If they don't **** up the speed, this should easily do well on the charts - just dancey enough for the clubs but just grown up enough to chart elsewhere. If they go all Guetta on it, down she goes
"Obvi", eh? Those RCA interns aren't even trying to sound official anymore apparently.
LOL but in all honesty, I kind of figured this would be a HIAM type of early leak and then the actual debut of the track would be much more different. I'm ready, RCA!
The song itself shows some urban influence and Xtina's soulful delivery gives it the FEELING of a R&B song, but it's just Christina singing soulfully over a POP song.
That "remix" is the final version 
It's a DEMO
