Omg. Prism is LITERALLY the born this way era. 
Roar = Born This Way - massive mega hit. 
Unconditionally = Judas - a song that everyone expected to smash, but it actually flopped 
Dark Horse = The Edge of Glory - the hit that gets the era back on track 
Birthday = You and I - decent performance, kinda local to the US
This Is How We Do = Marry the Night -
