LEGO Rock Band (check out our comprehensive preview), due out this holiday season, will offer over 40 songs. In keeping with Harmonix’s music platform ethos (and confirming an earlier rumor), most of the on-disc tracks will be exportable to PS3/360 hard drives for use in Rock Band or Rock Band 2. And they mean “most” -- speaking to me at a recent demo of LEGO Rock Band, Harmonix publicist John Drake took a thinly-veiled jab at Activision:

When we say we’re exporting a disc, we mean that we’re exporting, like, ninety-plus percent of the disc, not thirty-plus percent of the disc.

Of course, Drake was referring to Guitar Hero 5 and its compatibility with merely 35 of the 86 songs on the Guitar Hero World Tour disc. (Actually, John, that comes out to just over 40%, but we’ll let the semantics slide since you’ve got a valid point nonetheless.) He noted that he could confirm only “ninety-plus percent” because Harmonix is still working licensing the rest of the songs; they hope to allow for exporting all of the on-disc tracks.

[Update: Drake just confirmed to me on Twitter that Harmonix has secured licensing for 100% of the game’s 45 songs, so you’ll be able to play them all in Rock Band or Rock Band 2!] However the export key will cost twice as much as exporting Rock Band.
