Hi, thanks for letting us know about the problem. Sorry for the delayed response, for some reason I didn't come across this post when browsing the forums for new entries.
I see that the songs are currently in the free shop widget, so I assume it's no longer a problem. In any case, if you would like to know: When you click on the "Manage Your Music" button in the music section in the middle of your profile, you will be sent to the page with a list of all your tracks and some different columns with options by each track title. If you click on the Add to Shop button by the songs, the songs will be added to the Free Shop widget on your profile and will be downloadable.
Feel free to email me personally if you ever have any questions.
