Edit a wordpress template

Im currently using the Clubix V2 wordpress theme. I love the theme but want one minor change. Currenlty users are able to upload songs,albums,etc and then when they create "their" artist page they can select which songs,albums,ect want to be seen on the page. It currently looks like the uploaded songs are seen Globally. I want to only have the users be able to choose their uploaded songs, Albums, Events. I do not want to have them featuring other users songs on their profile. Is this possible? Check out [login to view URL] for more info. Click on the artist page and choose an artist to see what I mean.
