Internet Radio: Good music that sounds good, who do you like?

Folkalley.com. Commercial free out of Kent, Ohio.
This station will not  disappoint. 

I'm elderly and don't even know how to link .
A friend of mine set it up for  me . If you google  classical mpr choral stream
is on there .

@schubert - Were you actually going to name the station? Maybe post a link? ;-) 

As far as I know,  one that is totally unique in USA , perhaps in the world .

A 24/7/365 streamer of Choral Music of the highest level,  with the worlds best  choirs,  from  St.Paul/Minneapolis  PBS station .
Choral Music is HUGE in Twin Cities !

For jazz, try KMHD, 89.1, from Portland (Gresham), Oregon.

If you like electronic music I would recommend SOMA FM, they have a wide variety of channels, not all electronica, but that’s what I listen to.  My favorite is Space Station.

Radio Paradise is my favorite. Eclectic mix, very good sound quality. Over the last few years I've found more "new music" via Radio Paradise than any other source.

RadioParadise.  Commercial free and user supported.  Has some options to stream FLAC as well.
