Many RBN metal songs are being released on Rock Band with two versions. There's the regular version (which isn't marked in any way) and the 2x Bass Pedal version.
A 2x Bass Pedal version of a song is identical in all respects to the original version of the song except that the Expert Drum and Pro Drum tracks cannot be played on a standard Rock Band drum kit. They are created specifically for Expert Drum and Pro Drum players who have two bass pedals and can play nonstandard versions of the song.
To date, we have not brought any 2x Bass Pedal RBN songs to PS3. Should we? This poll is specifically to help me evaluate player interest (and disinterest).
