Despite
Glee's unpredictable plot twists in its third season,
Glee: The Music, Vol. 7 shows that its music is as reliable as ever, a mix of traditional glee club favorites with some seemingly risky choices thrown in for good measure. Songs like "You Can't Stop the Beat" and "ABC" are such typical, and effective, choices for the cast to sing that it's almost surprising they haven't been done already, but they underscore how
Glee, along with talent competition shows such as
American Idol and
The Voice, fill the void of the old-fashioned variety show in TV programming. The
Adele mashup "Rumour Has It/Someone Like You" rises above its tricky concept and features star turns by
Heather Morris,
Naya Rivera, and
Amber Riley. Likewise, the straightforward but successful version of "Constant Craving" shows that
Glee's music still has plenty of mileage when it chooses interesting songs for the cast to sing well.
