To purchase music online, a user becomes a member to a site which fulfils orders. An announcement is posted to members of a future release of a first song as performed by a first recording artist. Preorders are accepted from members indicating an intent to download the first song upon release for a fee. Verification is performed to determine that the member is eligible to submit the preorder. The preorders are tallied. A minimum volume of preorders is set. After the minimum volume is met, the first song is released. Members' accounts are charged the fee to access the song. By setting the minimum volume, a threshold revenue level is achieved for release of the first song assuring an established artist a minimum revenue regardless of any pirating that might occur after the release.
