You want to add one or even your own radio station to the default playlists? So to be available by default to everyone using the radio?
Then put it in a comment below after you have read the rules.

If you need help getting it to work, go there instead:
[Help] FAQ (Read this for help!)
[Help] Ways of getting stream URLs for the radio
[Help]How do I put songs in? (old)

1. The radio must be able to play it. Test it first! MP3 format is recommend. A few hints about what I mean:
   
   • No HTML, HTML5, Javascript etc.
     
   • No videos
     
   • No Flash Player things
     
   • URLs to raw streaming content
     
   • You already know how to add working custom stream URLs by yourself.
   
   
2. It must be a proper 24/7 online radio stream:
   
   • It should last for a while and not just one week. Do not create a station just to be added to this radio.
     
   • Make sure the stream URL will not change.
     
   • 24/7 means no silence time as well!
     
   • Don't use your home PC or your home internet connection for streaming.
     
   • Keep in mind that this addon has a relatively large audience (maybe 200+ listeners at once), make sure the streaming server is prepared for that!
     
   • It should be somewhat professional.
   
   
3. The radio station must have been already online for atleast one month without having serious interruptions (See rule 2) before submitting.
   
   
4. This addon has an international audience. So the language of your station must be english or neutral. The language of the station is defined by:
   
   • Spoken moderation/presentation/texts
     
   • Teaser clips or watermarks between or during songs
     
   • Station web page or station description
     
   • Staion name
   The the music and non-station-related advertisements can be any language.
   
   
5. It must be publicly available. No login! No region specific blocks! No pay-wall! No pay-to-listen! No warez!
   
   
6. It must not be files or YouTube content.
   
   
7. It must not containing any malware, warez, hateful, racism or otherwise illegal/NSFW content. Illegal stuff can get you reported and banned from steam! So, use common sense. Don't play the edgy guy! To avoid any problems the radio station (if it is your own) should be licensed to stream music in your country.
   
   
8. You can put in a playlistfile or an URL to the stream.
   
   
9. The stream should have a proper name. It shouldn't be called "myradiostream" or something. In case you can't change the name, just put the desired name in your comment.
   
   
10. Don't post something that has been already added to the radio by default. Check the playlists first.
    
    
11. A description of the radio station and what it is about would be nice, so I know what it is about. But it does not have to be.
    
    
12. I can change or remove added stations anytime if necessary or I want to.
    
    
13. Please, do not delete or snip your comment with your suggestions after they were added to the addon. If you do, I will remove the posted stations or even all stations from you. In this case there is a possibility that I would no longer accept any suggestion from you as well.
    
    If you want something removed you suggested just post about it instead.
    
    
14. Please post the valid playlist file if you got more then 5 stations to post. I recommend Pastebin. This makes it easier for me to add them to the addon.

If everything is fine, I will add them. You would see them after an update. The changes are applied by default. The playlists are saved inside the community folder. It's not recommend to change or edit anything in it when the auto apply is active.

If auto apply is not active, the server admin has to enter "sv_streamradio_rebuildplaylists_community" or "sv_streamradio_resetplaylists_community" into the server console.

What these commands do is descripted there: [Help] ConVars and ConCommands

• Valid and working URLs
  
• 24/7 streams that are somewhat professional
  
• English only (exept music or ADs)
  
• No illegal or edgy stuff (use common sense)
  
• Free and public to listen to
  
• Just don't be one of those guys and just read the whole damn thing above...
