At e-junkie, we have tailored our features to make our service especially useful for musicians.   For example, download links to music files are provided to buyers directly after checkout. And, there are few ways to sell your music with e-junkie: sell buyers your entire album, provide buyers with the option to purchase individual tracks or put up a bundle of songs for sale.  
To start selling your music with e-junkie, create your individual track products, by clicking on Add Product, located on the left side of the Seller Admin page. On the following page enter in the name of the track and the price of the individual track:
Then click the Submit button.  On the next page, at the top, use the Upload Product File button to upload the file to our server.

Once the file is uploaded, click the Add Another Product button in the lower right and add the rest of your tracks in.
Once all of your tracks are added in, you can create a bundle. When creating that product you will want to add a check mark to the box for Package Files From Other Products, Affect Their Inventory. This will open a window in the lower left that will allow you to select the products you want to be part of the bundle:
Make sure to set the price you want for the bundle or album and click the Submit button.
After that you will want to place the button codes for the individual tracks and the entire album on your website.

If you are a writer and you have a series, you can do the same thing, selling individual stories in a series or the whole series for one price.
