The American musical comedy television series is exceptional, refreshingly different, not just a normal teen soaps. The series produced for the songs of the "Glee Club" had already hit status and by the interpretations sometimes even better. Already there are a number of albums - with great success: more than thirteen million singles sold and five million albums sold (as of February 2011). Who bought a music CD, is certainly a second and third purchase [promised!] Also. For once, a film with good singing voices and not only good actors (I still think with horror of the vocals of Pierce Brosnan in the musical comedy Mamma Mia! By Hits of "ABBA"). The television series is one of my wöchtlichen TV highlights.
