There is no visible way to confirm if your DLC has been installed to your console until you first launch Rock Band 4 on that console. There will be no update to notify you that this content has completed downloading.Once completed, you should see that where the "Install" prompt used to be on this individual Add-On, it will now say "Installed". The download should automatically begin.If you purchased it previously, select "Install". There will be a monetary value on an individual Add-On if you did not previously purchase the product. Select the individual Add-On you want to download.Navigate to "Add-Ons" and select the ellipses (the big "." at the bottom of the featured Add-Ons) to view all Add-Ons.You will see multiple products for the title.Navigate to the Xbox Live Marketplace titled "Store".Sign in to the Xbox Live Gamertag that you originally purchased your legacy Rock Band DLC on.Here's how to re-download your Rock Band DLC on Xbox One: This means you can't do batch downloads within the first-party stores. This is due to first-party (Microsoft and Sony) "technical restrictions", developer Harmonix said in a post on its website. Depending on how many you need to re-download, that could take a lot of time. Here's the fiddly part: you have to re-download each DLC track individually in order to play the tracks in Rock Band 4. You can only re-download DLC for free within each console family, so Xbox 360 to Xbox One, and PlayStation 3 to PS4. Perhaps it will change soon, which we’ll update this guide for.You can now re-download previously bought Rock Band DLC ahead of the launch of Rock Band 4 - but it's a bit fiddly. Rock Band 4 is still new, so this process is still being worked on. It really is a pain to have to do, but it’s better than not supporting the old DLC at all, or making you re-buy it all. This will upgrade the song to your Rock Band 4 account, and add it to your game. Find each song you want to import to Rock Band 4 and essentially re-buy it for free. You’ll actually have to go into the PlayStation or Xbox Store, or just go to the Rock Band Store on the game itself. Unfortunately there is no process for re-downloading all of your DLC.

Now, that handles the export/import from the main games, but what about individual DLC. Just enter it into the system as normal and follow the same export procedure. If you’re nice enough, and lucky enough, they’ll give you a key.

Tell the rep that you need one, they are actually listed under Rock Band 3 so be specific that you are importing RB2 songs into it. By contacting EA support you have a chance at getting a key. You see, official support for exporting has ended, but there is a way around that, at least for now.
