SMS is far from being the worst, it's the only real "banger" on this album.
Mileys vocals and faux-rapping is seriously embarrassing and the "Bangerz" echo effect is dumb. Britneys verse isn't even memorable either and i would've thought she could salvage the song and be its saving grace but she isn't. I hate the Push It sample, its all just so bizarre and not even in a good way at least. Its awkward.
Britney's vocals alone>>>>>>>>>
