Come on, it's not that hard to use it correctly and pick the term from the list
How does google know the difference between 'song' and 'search term'?
Bad Romance the 'search term' has far more searches than Bad Romance the 'song', but the 'search term' didn't get any searches until the song was released.
Maybe Tik Tok is more remembered than BR but BR is def not forgotten. If everyone here in Russia still knows and remembers that song how can it be forgotten is US, UK or any other country?
