Glee

It has a great cast, interesting storylines, witty humor and well-delivered lines of dialogue.

But one of the main reasons why Glee has become a phenomenon on Fox is due to the show's soundtrack, a version of which will be released on CD on November 3.

Fans aren't waiting until then to purchase singles from the musical comedy, however. The cast version of Queen's "Somebody To Love" - which was featured on last night's episode and released on iTunes last week - has already landed in the top 20 most downloaded songs online.

That's nothing compared with the series premiere rendition of "Don't Stop Believin'," which shot up to number-one; or Lea Michele's "Take A Bow," which peaked at number-six.

All these numbers are available to buy in our Glee music section. Browse through it now and watch the cast rock out to the aforementioned Queen hit below:
