downbeat 

1. The first beat of a measure of music. Refers to the downward motion displayed by a conductor on beat one.

2. In the music industry, the time when a recording session or live show is scheduled to begin. Everything must be set up and ready to go before this time. Often ignored by big stars with bigger egos.

1. After the grand pause in measure 30, watch for the downbeat.

2. The downbeat was at 10:00, but the singer didn't even show up at the studio until 12:00.

downhearted 

Utterly apathetic, as the song by Primitive Radio Gods: PhoneBooth proclaims "i've down hearted baby ever since the day we met"

totally without care, beyond depressed.

"As the prince comes to claim his kingdom, and his lover.... he finds everything is destroyed,and his lover killed, he will forever be downhearted"
