Rock Band Blitz is set to disappear from the Xbox and Playstation digital stores on August 28th.
Developer Harmonix has explained that the game’s removal is due to expiring licenses on the music in that form. However, all the songs included have been released as DLC for Rock Band 4, or can be imported into Rock Band 4 from Blitz. For information on how to import the songs visit this page from Harmonix. After the delisting, not even the demo for the title will be accessible. Additionally, Harmonix confirmed that Rock Band Blitz will not be joining the Backwards Compatibility program on Xbox One.
Rock Band Blitz debuted worldwide on August 29th, 2012, and featured gameplay that was solely on the standard gamepad, similarly to the PSP’s Rock Band Unplugged.
