downloading apps if appstore is restricted

If you want to download apps via computer it has to be from iTunes but not just any sort of app it has to be a app which has some link to do with music (i.e., Spotify,SoundCloud). If you want to download apps but the App Store is restricted all you have to do is go to Settings>General>Restrictions>Enable Restrictions then type in your restrictions passcode i.e. your passcode and go click on apps and unrestrict it!!

Can/would you explain what you mean by restricted?
