SoundCloud is a horrible music platform for the large majority of emerging artists that try and make it big, aside from the few that were able to get lucky on the platform. For an artist to make money from the streams of their music on SoundCloud, they would have to pay eight to sixteen dollars a month for a subscription, or what SoundCloud calls a "hosting service."
Also, because of how badly the interface was made, artists can easily manipulate SoundCloud to make their work seem more popular with the algorithm. SoundCloud allows users to repost certain songs they like and also does not have sufficient checks on how artists post their work. This has allowed many artists to get away with making entire accounts dedicated to reposting their music and to posting the same song over and over again to get it more attention. This means that artists who have not discovered these glitches in the interface or just do not have time to exploit the flaws of the platform have a much harder time succeeding on SoundCloud.
