Telephone may be generic but you tell me the next person you see who doesn't know all the words, even beyoncé's part. Eminem may have helped to make the song, but most people only remember the chorus.
I love me some GaGa but only on ATRL do the members know the words to Telephone better. In the real world, LTWYL is much more popular. The hook alone is magical and memorable and everyone usually tries to memorize rap songs so they can impress their friends when drunk, do it at karaoke or just cuz Eminem is KING and his lyrics are flawless.
