Debussy is an amazing composer. When his songs come on our Classical Radio Station (a station I call "the most consistently tolerable" in the face of 100-too-many Top 40 Stations) I can easily let my mind go somewhere more pleasant.
I'm also a huge fan of Ravel. He's also well adapted by other performers:http://youtu.be/GKkeDqJBlK8
(Pavane for a Dead Princess; the 1 minute area is so poignant yet romantic...for a song about a "dead princess" the piece is surprisingly uplifting and relaxing)http://youtu.be/E05l9LSYoyw
(And a version of the song from Breath of Fire IV...which was somewhat surprising to hear IMO).http://youtu.be/LWcpw3GAAms
(Same song by Pink Martini -- who give it a jazzy swing)http://youtu.be/SqjqvkAXXD8
(By Angelique Kidjo, an African singer who did this brilliant acapella version)
