Earlier this month the Evergeen Park Soundtrack Albums were removed from the U-Music Store due to legal issues with LittleBigPlanet. However, now they are free to preview (but not available to download) from the same place as they were previously.
T-Games and U-Music will contact LittleBigPlanet to try and make the music available to download to the public. But for now they will remain un-downloadable.
