"Glee" at 10: The 10 Most Memorable Musical Numbers We're Still Singing Along To!

3. “Rumor Has It/Someone Like You”

"Glee" covered a few Adele songs and various mash-ups, but nothing compared to this emotional performance. It has my all-time favorite character Santana (Naya Rivera) and the power vocals of Mercedes (Amber Riley) and is so emotionally charged because Santana is struggling with her sexuality in the show and is terrified of the rumors and everything being said about her. You can feel the pain in the vocals, and the slap at the end always gives me goosebumps.
