Unlike on other platforms that have access to most every song in the franchise's archives, Rock Band 4 for the PC comes with no previous DLC content. As such, Harmonix has added an additional tier to its fan-funded Fig campaign that would give backers at that level every single song in the Rock Band DLC library. The only hitch: you're going to have to shell out a whopping $2,500 for it. Well, that and the campaign still needs to raise another two thirds of its $1.5 million funding goal in the next 11 days.
