I have downloaded a few songs from the music store in The Beatles: Rock Band but I am running out of space on the Wii memory. I have an sd card and want to put those downloaded songs on it but I'm unsure of the process. If anyone can give me step by step instructions (or direct me to a place that can) that would be awesome.

P.S. If I get those songs on the sd card, could I then take the sd card over to my cousin's or neighbor's Wii (along w/ the game disc, of course) and be able to play the downloaded songs there as well?

Thanks in advance for any helpful answers!
