FF tour production was lame compared to the Circus Tour
It's pretty clear that they didn't invest that much money on the tour, and in the whole era as well.
Not to mention how the stage kept getting smaller as the tour went on.
'Wake Me Up' would be so perfect for Britney, lyrically as well.
It combines EDM with a bit of alternative sound, which GP seems to be loving right now.
Hopefully Avicii can produce something like that for Brit.
I can't say the same about her 4th tour
