Reddit is a social media site. Among its various sections is a large /r/Music subreddit group. Most of them link popular or novel Youtube music videos, or user-produced content etc. Radioreddit.com even provides streaming servers. This plugin can also list Soundcloud/Mixcloud/Bandcamp links. But those would require a custom audio player. There's an extra Soundcloud plugin however, which makes those streams readily playble.
"Digitally Imported" are mostly electronic music radio stations. The freely available stations stream with 64kbit/s AAC+ only.
Radio.net is a European radio directory. It nicely catalogues stations into genres as usual. The primary list is ordered by popularity even.
Magnatune is an independent label for artists. It makes most albums available for free listening with only a few intermittent adverts. Otherwise it's a flatrate payable music discovery and download service.
PublicRadioFan.com hosts a huge lists of worldwide radio stations. This plugin displays just the genre list though.
Is actually a Windows-specific streaming directory. Station entries are converted from ASX into standard playlist formats by ST2.
Delicast.com is another web directory of radio stations. It's somewhat slower because playback addresses are hidden away with extra page requests. Works reliably still.
ListenLive is also an Europe-centric radio directory.
PunkCast is no longer maintained. It covered the NY music and tech scenes, but existing recordings are still accessible mostly (some are just weblinks howeever). This plugin is kept for nostalgic reasons; it was available with streamtuner1 as well.
