This must be commented before, but since I'm not a Glee fan, I didn't know so it was unexpected to me.
Of course I watched the Rumours Glee episode at the time, everybody (here) was talking about it. But today I casually saw another old episode where Gwyneth Paltrow sings Landslide. I've never seen that, it was a nice performance.
Cool to read later than MTV said that song is a treasure of the Fleetwood Mac catalog.
