The easiest way to find an audience is to add other users to friends. Almost everyone will accept and listen to your tracks. However, the site has a limit – you can add no more than 2000 people. What to do when you already have 2000 friends? You just need to unfriend some of these users, and then add new ones. The main thing is to try not to delete or add the same people several times, but the site is so big that you won’t be able to do it.
There is also a limit on the number of friends added per day. Don’t annoy the mods, but add friends gradually, 50-100 people a day. Then the system won’t be angry with you and ban you for a day or more.
Where you can look for friends? It is best to do it in theme communities. Join all the communities that are close to you by genre. Add to friends all of the members of these communities.
Likes and comments help to attract attention of other users as well. But here the main thing is not to overdo it.
Now, a little bit of statistics.
I created my community on this site in the end of September 2016. At that time, I didn’t have any subscribers at all. In 2017, I had 1140 users as my friends, and our tracks had been listened up to 1700 times!!! People wrote us 77 comments. In one month our music was downloaded 13 times, until I blocked the possibility of downloads, to stimulate sales. By the way, you can download music from Soundcloud here http://soundcloudmp3downloader.com/. Well, the most important result is that a few users clicked on the links and bought our music from online markets!
