Songs during Glee

I like the songs in Glee but not so much the storyline and drama. If I can figure out when the songs typically occur, then I can tune in when there is the greatest probability that there will be a song and not have to sit through the drama. The best chances of catching a song appears to be 11, 27, and 41 minutes into the show.

Average number of song per show: 6.2 songs
Average duration of songs: 1.8 minutes (stdv of 0.6 minutes)
N = 6 shows
I know I need a larger sample size, anyone wanna help me collect data? :)
