I think Jordin's sales could be increased if the younger kids heard Tattoo more. Maybe their parents don't let them listen to Top 40 stations. For example, Radio Disney doesn't even have her listed as an artist, and Tattoo is not listed on their song list. You could make a difference by going to Radio Disney's website and on the song request page, click on "song not listed" and then type in Tattoo and Jordin!!!! Here's the link:
