To make matters worse, the song was horrible. Why not just perform Super Bass or whatever new pop single she has. That was just...dumb.
It goes back to pop music being pure spectacle instead of actual talent. The show is almost meant to distract viewers from the lack of quality in the music, lip syncing, etc. Thank Madonna, Britney Spears, and a host of others. Some would put Gaga in that category but she's actually the most talented pop singer in ages.
From the bits that I saw, Adele and Jennifer Hudson had the best performances. Stripped down, no spectacle, just straight up shows. Meanwhile Minaj went crazy, Rihanna had a bunch of shit flying everywhere, etc.
