Soundtrack
Lego Rock Band's 45-song soundtrack was selected to be "suitable for younger audiences", unlike those of other Rock Band games. The Nintendo DS version of the game features a 25-song subset of the songs in the console versions.
The Lego Rock Band Music Store includes downloadable content (DLC) from the standard Rock Band Music Store which has "been identified to be suitable for all ages". Also, any songs exported from the original Rock Band and its Track Packs deemed "Family Friendly" can be used in the game. All songs available in Lego Rock Band are compatible with other entries in the Rock Band series and can be exported to those games for US$9.99 along with the use of a unique code included on a paper insert included in the game case. Songs from the Rock Band Network cannot be played in Lego Rock Band due to the songs being unrated. No songs released as DLC after Rock Band 3's release are compatible with previous games, including Lego Rock Band, due to changes in the file format. The Wii version of the game cannot use any downloaded or exported songs, and its songs cannot be exported to other games.
