For a while I have been tinkering with the idea to combine Steem Transfer Memo's to automated processes and do more with the Steem Blockchain write/post possibilities in a useful manner.

Up to now I had only been making apps which are certainly fun (imho), and display read data from the Steem Blockchain, but that all changed today... Introducing RadioSteem.com

RadioSteem - Consensus Radio Station

By using the possibility of attaching a memo users can supply a request to have their favorite tracks added to the random playlist of the radio station.

Whenever a new track gets added it will (only once) play directly. New tracks are added every 6 minutes and crossposted on @radiosteem 's blog.

Currently the radiostation is in 'aggregation' modus and randomly plays all added tracks.

Over the weekend I will flip to 'consensus/vote'-based picks for the hourly random playlist instead of 'fishing' from all tracks added. You can simply bring your vote on @radiosteem 's blog which lists all tracks added to the playlist.

I have prepared the 'playlist' items on @radiosteem 's blog with special json metadata, you could inspect individual posts on Steemd.com to see that metadata!

How to play Radio Steem:

An icecast streaming server (mp3) is broadcasting on the interwebs and you can play this in your browser, iTunes, VLC, Sonos, laptop, phone, etc.

Play online via http://RadioSteem.com (with overview of nowplaying, amount of listeners, and recent requests)
Direct m3u playlist file: http://radiosteem.com/radiosteem.m3u
Direct xspf playlist file: http://radiosteem.com/radiosteem.xspf

How to add your track to Radio Steem:

Go to your Wallet via the menu.
Click on your totals of either SBD or Steem and initiate to transfer money.
Fill in the transfer dialog: Send at least 0.33 SBD / STEEM to radiosteem and fill the memo field with artist track. Replace 'artist' and 'track' with your favorite artist's track. ~~Don't forget the play keyword!~~ (Update: no longer necessary to begin with 'play')
Hit transfer, you will be asked to sign with your 'active wif' or overall password, leave 'remember me' unchecked.
Wait a bit... The machine processes 1 request per 6 minutes.

Royalties

For now this is a (fully working!) proof of concept, if it works it will be finetuned. I have already investigated the webradio licensing fees for running this kind of station. If there is a decent request for this station, or other streaming music ideas which could evolve from this, I am happy to pay the licensing fees to the local royalties collector... ^{This royalties collector will then use this fee to pay their CEO's villa and ferrarri and leaves some pennies to the artists. :(}

How It Is Made:

Server
Piston.rocks python-steem library by @xeroc
User requests via 'memo'
Script looks up and normalises data via 'ye good ol' Last.fm API.
A certain provider of clips, fail vids and what more supplies audio.
Instantly streams the newly added audio.
Afterwards picks next added track or random from the list.

Notes

@radiosteem wires your money back if no track was found
@radiosteem wires your money back if you wired not enough money (minimum = 0.33 SBD or 0.33 Steem)
be sure to upvote your track on @radiosteem (note we most probably don't earn author rewards because we cross the 4 posts per day easily)
