Yes!
If you have the Musician Plus or Ultimate plan, you can specify the price of your track or album on iTunes & Amazon.
If you don't specify your price (and for non-iTunes/Amazon.com stores) your music will sell for whatever the stores' default pricing is. For example, as of this writing, singles are 99-cents on iTunes (you keep 70-cents). Both you and the stores want to sell as much of your music as possible. Allowing stores to determine pricing may net you the most sales and money.
Please keep in mind that we will send your specified prices to iTunes & Amazon, but they do have the option of overriding this & setting their own price.
Stores like iTunes may set a higher price for singles that are longer than 10 minutes in length.
