Recently with the World championship being disputed and the leagues of League of Legends being played during the seasons, there is a market of people that would like to hear the music they play during the streaming of the matches.
You can find the songs here:
There is a long list of commercial songs that doesn't exist in spotify but yes in other places like Youtube.
I among other people would like to see this songs and more likely a playlist of them. But for now we would be happy just with the songs.
Thank you very much.
