Does your pet listen to your system?

Not sure if this has ever been a thread for discussion.
We have a pet cat.  Her name is Mina.
She sits in the sweet spot, on the floor, when my system is running, playing music.
I swear she likes to listen to music! 
No, she doesn't tap her paw on the ground or anything like that, but to me it looks like she enjoys the music!
Anyone else out there have a pet that listens to music with them?
No official study, just curious.......
