If you buy this album, the artist gets all the money. None of it goes to "The Man" or some studio bigwigs. Even if you pirate most stuff, consider supporting a starving artist.
Don't buy that candy bar/hamburger/beer, stay healthy and support an artist who really needs the money. Really. It's four euros. That's like five bucks. Bandcamp doesn't take a cut, so all of your money goes to the artist and the donation.
