Billboard Music Chart For Animals

Supposedly cows will gather around and listen to music played in their pasture through loudspeakers. They evidently prefer country. They also rush to hear accordion music.

There's an ostrich that dances to flute music. I've included a vid link but simply Youtube "animals listening to music" and you'll see dozens of posts.

So it would be fun to compile a greatest hits chart of various animals. Gauge the reaction to various songs. Do ferrets like Slim Whitman but run away from the Sex Pistols? (Like most of us would.) There are various ways you could test this. Put 4 speakers around the pasture for instance and see where the sheep go to listen to the 4 different songs playing. Rotate the songs to account for other factors in the field. Do they follow a particular style?

Do animals have shit taste in music simply reacting to any sound or is there some level of critical listening going on here? Do different animals have different tastes? This would be interesting to look into.
