Glee manages to pack an insane number of songs into each episode, which means there will always be a few standouts... along with the inevitable dud or two. We've narrowed the performances from Season 3, Episode 10: “Yes/No” down to the very best and the coulda-done-without. After all, not every Glee cover can hit #1 on iTunes!

Best Performance of the Night: “Without You” by Rachel

Talk about powerful! Rachel (Lea Michele)’s stunning vocal performance manages to even surpass Usher’s original version, especially on those high notes. (We still love you, Usher.)

Worst Performance of the Night: “Wedding Bell Blues” by Emma

This song barely edges out Artie’s high-energy but somewhat out-of-place Jagger-themed mash-up for this “worst” slot. We love that Emma (Jayma Mays) gets her time in the spotlight — especially with Sue (Jane Lynch) and Beiste (Dot-Marie Jones) hilariously backing her up — but this lightweight trifle just can’t compete vocally with the week’s other songs.
