I liked some music in labor. I made three playlists:
slow, hippie, peaceful songs, most being just instrumental or quiet
fast paced songs for dancing, movement, early labor
ballad-type songs I can sing along with for focus on something outside of myself
All that being said, I hardly listened to any of them in labor. Ballad songs got the most usage as singing gave me a focus point outside of the surges in-between active and transitional parts of labor.
