I’m sorry that I’m asking many questions but this will hopefully be my last one. Only last night I just realized that about 25% of my song library would be unplayable if I remained offline, and this is because this is not the first Xbox I have had (or I got a new hard drive, don’t remember the case).

 

So to validate the song’s licenses, I have to go back into the store and re-download them. This also means I am forced to download update 5 to achieve this. Provided I move my custom song out of my system, is it safe to go online and re-download the recent update?

You can also do it using the RB Music Store standalone app, iirc, but worst case scenario just delete TU5 when you’re done playing around online. Maybe back up your TU4 save file ‘just in case’.
