ugh, its so BASIC. and not even the good kind of basic. She's straying off herself more and more with each release. But the "What are you waiting for" vocals are a welcome change from her greg kurstin robotness.
The fact that this song is #49 on iTunes UK right now is HUGE. Usually, when soon to be #1 songs are in the pre-order stage, they tend to reach the 40s the days before their release. These songs that get that high in pre-orders shoot straight to #1 when they are officially released. The fact that Love Me Like You Do is already #49 on pre-orders more than a month before its release likely means that it will be a huge success there.
