@vancha is shoutcast still going? Wikipedia says proprietary, but I'm pretty sure it's a tcp socket which spews mp3 as soon as you connect.
Old episodes from the http://ratholeradio.org/ podcast have conversation mixed in, but are amazing and worth listening to.
Otherwise jamendo (as others said), or https://cchits.net/
@h2g2bob it seems to still exist, thanks for the tip :)
