On our Equinox cruise, there was a DJ at the pool with very limited live music.
Oceanview is open on a limited basis after 9 pm. Mainly bland pizza, pasta, salad and fruit bars, and desserts. No sandwiches.
Most of the action at night takes place in the Plaza with live music and dancing. Not like my experiences at Royal Caribbean.
Comedians are hit or miss. Each one will usually have an Adult performance late one evening.
