The Rock Band music store is now open for business on Wii. The store (Xbox 360 version pictured) launched today with 50 songs, including Rock Band 2's 20 free bonus tracks. Harmonix notes in the Rock Band forums that more DLC will be released in the coming weeks to "catch Wii users up with other systems."
A list of the released tracks can be found after the break. The free tracks are in bold and the premium songs are 200 Wii Points ($2) each. Welcome to 2007, Wii.
