Go to indiecharts.com and log into your Indie Charts account. On the page header, select the "upload/edit music" link, at the fifth slot counting from the left of the header. For security purposes, a pop-up window will prompt you for your log-in information once again to allow you to enter the "upload/edit music" section of your profile.
Select the "move" drop-down box to the right of your song names to change the songs' rotation. Your songs' rotation should be your first priority because they are reviewed in chronological order based on the date of the upload. You have the option of editing your songs by either deleting, renaming, or uploading new songs, all of which you can complete on the bottom half of the editing profile. Each of these edits affects the overall display of your music in your profile.
Save the changes via the loading bar icon located in the lower right section of the pop-up window. The saving function immediately processes the edits. Close the pop-up window and when you're back on the main page, refresh it. All edits will display in the song display box in the middle of your profile screen.
