It's been 4 years since these two No.1 debut lead single from the legendary Queen of Pop, Britney Spears, and the mother monster, lady Gaga, in early 2011.
When both singles were just released, the army and the little monsters went wild and billboard created a poll on their website which BTW won at first which the army thought there were something wrong with the poll and demanded a new war which they won.
Note: both songs debuted at no.1 and broke digital and radio records. HIAM set dubstep trend and BTW was a gay anthem of that time.
Question: which song do you like more now and sound fresher?
Let's the war begin!
