I know a lot of artist are wondering about this how to make money with music and the arts with the internet with such piracy like warez and torrents around, and as the main internet founder I am going to answer this one burning question for you straight of the bat.
You make money from add-on sales, how this is done is your album or song you release as creative commons (cc) which means you can store the download under the creative commons licence on sourceforge.net or github.com — I would recommend sourceforge though cause you can have a git or SVN on there that is private as an off site backup of all your samples and audio loops etc.
You then go to china, and order printed USB Flash keys you will only need 1GB for an album that also contains a file called LICENCE that has the creative commons licence on it, with your audio files, these are for direct distribution, you know at a concert everyone gets a copy of the new album, you then place links on the USB to your online for example zazzle.com site both listed in a windows *.url file as well as the README file as well as FILES.DIZ file.
You can also make a track that is an audio advertisement for you in buy my t-shirt support place and play, you can still collect royalties for radio and major media play but the true way of making money in any retail environment is add-on sales, ask any retailer about this they will put down the hammer and tell you that is on the spot.
Not only does this also give you a wider birth of distribution your immersion and take-up of a new album in retrospective to album closed licence sales is millions and billions to only having 1 listener.
This is very similar view to punk rock like the southern records distribution that was at cost like albums for 45p of the Crass which we all know because of this.
