One notable re-entry next week [Billboard Pop Album Chart] might be Fleetwood Mac's "Rumours" album, which is profiting from the power of Fox's "Glee." The TV series dedicated its entire May 3 episode to the 1977 album -- which spent 31 weeks atop the chart. Six of the set's 11 songs were performed by the cast, while another was heard in its original form as background music.

LOS ANGELES (Hollywood Reporter) – "Glee" has tipped its hat to Broadway, Lady Gaga and classic rock, so why would the Fox hit -- whose goal is to stress the importance of music education and appreciation -- cover Rebecca Black's much maligned "Friday"?

"There's a rule for it that's explained in the show," "Glee" co-creator Ryan Murphy told The Hollywood Reporter. "The (glee club) is hired to perform songs for the prom and they were told by the principal to please do popular songs that the kids know."

Black's heavily autotuned song became an Internet sensation for all the wrong reasons and landed its 13-year-old singer death threats. The YouTube clip has garnered more than 133 million views.*

Murphy noted that Glee's "Friday" cover -- performed by Puck (Mark Salling), Artie (Kevin McHale) and Sam (Chord Overstreet) -- offers a different take since it's sung by males.

"It's songs that supposedly 17-year-olds are performing for other 17-year-olds," he noted. "I think younger kids have a definite reaction to that song."

He added, "The show pays tribute to pop culture and, love it or hate it, that song is pop culture."

"Glee's" prom episode airs Tuesday on Fox.

Just give Jayne Lynch the Emmy now. Nobody else need apply.

With Kurt, Rachel and Finn all being gone after next year how watchable will Glee be?

She said the theater was pretty empty. How were the crowds when you saw it?
