Learning Finnish...

Hey guys, I plan on transferring to Finland for college, and majoring in ethnomusicology, however in order to gain access to better courses and not the whole "immersion" shit, I need to be fluent in Finnish. I've got some websites that are pretty useful, but i need something on the level of "rosetta stone" that will help me along in my daily practice. (I might also take lingusitics )

Can you good fellows suggest me something? Thanks /lang

You don´t need learn finnish because everyone here (in Finland)
speaks english...
