The order albums are displayed on your store can be managed via the albums page in your library
How can I change the album order?
To change the Album order, select the 'Set album order' option
From the drop down, you can choose to display by 'Newest first' or 'Oldest first' or you can 'drag and drop' albums to a new position by clicking on an album, holding down the mouse and moving the album to a new position and releasing the mouse.
When your albums are in the order you like, remember to 'Save changes' to apply the new order to your store albums.
