Music - Music - Music

Dear fellow Yoga teachers,

I have found music to be a challenge for me. I want the right music for the class and the right music for the right flow. I want the right music for the chapter we are in.
I have been challenged to get the music right and challenged to be satisfied with the music.

For my classes at work I have been staying away from music that is too yogic, too devotional. Then I have been disappointed with my music collection. Then I want the right song for the right moment in the class. I am over analyzing it.

Does this get easier? Yoga teachers - what is your plan for music? Yoga students - what are your expectations or what do you like?
