Simple online listening

There are many free streaming radio stations but most want you to listen via their web page media players. This involves advertising in its many forms, visual and aural. I prefer to use a simple console based bash script that eliminates the garbage by invoking native Linux utilities that don't eat up processor and video resources. Something like...

...that produces only music.

Google searches do not result in any meaningful hits on such broadcasts. Can anyone suggest where I might find a list of useful stream addresses?

Thanks in advance.
