2. Format the custom songs correctly. Custom songs must be in the correct format in order to be imported into Rock Band. The songs must be in either .psarc or .ps3 format. The easiest way to convert your songs to this format is to use the "Import" feature in the Rock Band 3 Game Addon Exporter application.
3. Copy the custom songs to your PS3. You can copy the custom songs to your PS3 using a USB storage device, such as a flash drive or external hard drive. To do this, simply connect the USB storage device to your PS3 and then navigate to the "Music" folder in the Rock Band 3 game menu. Then, select the "Import" option and find the custom songs on your USB storage device.
4. Select the custom songs you want to play. Once the custom songs have been imported, you can select them to play just like any other song in the game. To do this, simply go to the "Songs" menu in the Rock Band 3 game menu and then select the "Custom Songs" category. Select the songs you want to play, and then start a game.
