I think Ooh La La will be much more polished, also less little kid sounding. It's definitely going to have some substantial changes otherwise they would've just released it last month as soon as it leaked?
"Till the World Ends" was supposed to sound different...
Where are each of those songs from? I know they're either from Oops! or BOMT but I'm not sure and I want to add them to my iTunes library but to the proper albums.
