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.......
An ex-girlfriend had a fidgety, whiny cat that would stop dead in its tracks and listen whenever Johnny Cash's voice came on.  If it was a duet, it would only sit up and pay attention when Johnny was singing.  
My dog will lay down in the middle between the speakers the moment the music starts.

Well I'll be!
I had a hunch I wasn't the only one that had a pet that listened to the stereo!
Ha!  Now we need some expert in pet psychology to explain why they must like certain music types over others......
He really likes "Good Morning" by the Beatles.

So ozzy s dog likes good stereo separation like Mina does!
