@CalvinHarris: Check out the FREE 18 Months app! https://t.co/LUcaGByN

I wonder if Gaga will tweet about this.

Isnt this Gaga's idea for ARTPOP?

omg ARTPOP APP rip off!!! calvin harris starts a war.

Bjork was the first to do this not gaga or calvin bye bye.

Yhopefully it unlocks We found Love Part 2!!

Only available in uk.

If ya'll read the description it's basically a workout/exercise app...as you move, the songs from his 18 Months album play...if you stop moving, the songs stop playing


It's nothing like what GaGa described the ARTPOP app to be

omg

That's actually pretty cool tbh
