Digital Distribution 101
Okay so I thought I better let ya'll into a "not so big secret" about digital distribution.
If you want iTunes to "stock" your CD, you have a few options as to how to go about getting your music on there.
Option #1. Directly set yourself up as a music provider with Apple. This involves applying to Apple for distribution as a music label. The most long-winded approach (though you'll make the most money).
Option #2. Get someone in NZ who already has a hookup with Apple to do it for you (this usually involves a fairly hefty commission). Loop does it, and they take 20%.
Option #3 (This is the best one). Get CDBaby to sort it all out. This is the same pretty much as option #2, except they're based in Portland, Oregan. They also distribute your record to shitloads of other online music stores, and only take 9%. They're pretty freakin' awesome, really honest, and really fast. You can sell physical CDs there as well. The Tweeks have had some success with them, and the Julian Temple Band (though probably under the JuJu Crew name) by all accounts have had good success.
I post this because I just checked The Tweeks' digital distro on CDBaby, and we're on all these. Awesome huh?
