I tried this approach and got a lot of gibberish on the screen.

I tried mpg123 http://linux10.cs.uaf.edu:8000/kuac16mono
and it played me the Fairbanks university radio station, loud and clear.
This particular station had instructions how to deal with .m3u and .pls 
formats and it also gave the above line.  This was my one success.

I downloaded some .mp3 piano music from an mp3 download site, which was 32 
K/sec encoding, and played it here and it sounded okay.  My download speed 
from this site varied between 0 and 3.2K, so when I tried to play it 
streaming it sounded rather awful.  Each note repeated about four times in 
a row, in short bursts.

The above seems to write to standard output, not play the file.
mpg123 http://......../filename.mp3 worked (except for connection speed).

mpg123 told me 'junk at beginning of file' when I tried to play files 
ending in .asx or .m3u.  Files ending in .pls gave me information about 
the file and not music.

I then read that .m3u and .pls are the currently fashionable formats for 
streaming audio.  Fairbanks has links for both of them but also worked 
with mpg123 somehow.

So I need to find some URLs with :8000 or :8080 for streaming mp3.  Maybe 
I should search on these string plus 'classical'.  Maybe the URL is the 
'junk at beginning of file'?

Is there some easy way to find the links without downloading the .m3u or 
.pls file?  I am at least armed with more information (I know what sort of 
URL to look for in the file if not online).

SW7.1 mp3.tgz contains version 0.59r (the one you are warned not to use). 
The site provides 0.59q for rpm and probably this is more secure.  I hope 
the security problem pertains mainly to people with broadband and/or 
servers.

I cannot be prepared for all sound cards.
