We had a similar incident on the Silhouette in November, 2022.
We had "Select" dining so we were seated upstairs.
Every night for the 10 night cruise there was a very large group that sat downstairs and they would sing along with staff of 3 musicians and singers and they would sing, very loudly, with live music, "Take Me Home Country Roads".
The first time we heard it, it was cool, but c'mon, every night, 2-3 times, enough is enough.
