A: Possibly. Some rips leave the "User Tracks" folder functional. You can add your own MP3 files to be played as radio. However, the scripted radio DJ banter is permanently gone.
Remember: If a file size seems too good to be true (5GB -> 0.2GB), it almost always comes with a heavy price—either your data security or your gameplay experience.
Drive safely, CJ. And avoid those Mediafire links.
