I think it has a certain degree of universal appeal. It has really aged extraordinarily well. If you are ever given the opportunity to listen to it on an any type of hifi system, do so. You'll find layers of eery texture and masterful use of stero dynamics. As a cherry on top, the album forms a perfect loop.
As for a song, Aphex Twin's Avril 14th. I love that you can hear the action of the piano in the track. It was recorded with a kind of player piano that makes it sound very mechanical, but it still has a somewhat organic feel to it. It's very quaint yet oddly contemporary.

Check out this reharmonization/improv on Chopin. The guy was basically blind, hence the insane awareness of where the keys were.
Song: Wildflower, by Skylark (fun fact: David Foster was a member). Here[0] is a live version. Here[1] is the background story.
Honorable mention: Hoptsoi, by the Finnish group Värttinä. OMG, the strings. [2]

Most beautiful album is I guess Keith's solo piano Facing You. Doesn't seem to be on youtube at the moment. This is one track from it, Ritooria https://www.youtube.com/watch?v=zVpDWxoFGP4
Medieval style is rather beautiful.

Steely Dan's "Home at Last" is another interesting turn on Odysseus.

My favorite piece of all time. It encapsulates what I want to feel about life
One of the only songs where I prefer the live version to original studio
