I noticed this not only in Techno but other electronic music genres as well, a lot of releases can only be bought on Beatport and I always wondered why that is. I once read that Beatport is quite awful at paying labels and artists and keeps a lion share of the money. Now I have to say that I never distributed self produced music anywhere so I'm genuinly curious. From a customers perspective, I prefer Bandcamp over Beatport in basically every way. I can listen to the full songs beforehand, the prices are generally more reasonable, I can download every purchase I made at any point in time and in every available format (plus, there's no stupid catalogue-prefix on every single track).

So what's the reason behind this? Does Beatport have exclusive deals with so many labels? If so, is it even worth it for the artists and labels if Beatport keeps so much of the revenue (again, which is something I heard, but I'm not sure of it). Or is it an exposure thing since Beatport is the bigger platform?

Any insight would be appreciated, thanks in advance! :)
