I don't like Soundcloud actually. So many people there just desperately want to increase their amount of followers. It turns into an extreme "follow me, i follow back" circlejerk game where following becames meaningless in the end because nobody is genuinely interested in the music.
On the other hand i think bandcamp makes better decisions overall, their tagging system is wonderful to explore music, there are no follower numbers to boost anyones ego. By default it promotes donation to artists, and the audience is actually very willing to pay even when you offer it for free (i was surprised myself seeing someone pay 6€ for my album that was free to download). All new music i listen to in the last 3 years is from bandcamp, either indie labels there or individual artists, but that's also due to the fact that i'm very involved in niche/micro-genres that basically has their releases and community entirely on bandcamp mostly and not on the "traditional" music market.
