You're right in respect to thinking English words can be substituted for German words, I don't know what I was getting at with that, mainly that everything doesn't translate over exactly the I thought it would and it's confusing. I do understand that things won't translate over as well as I thought they would, some words may not translate over at all.

I do play two instruments (well haven't actually touched mine in a couple years), so it is interesting you mentioned that, musical ability and language learning/ability use similar parts of the brain. I can't sing so I don't actually sing to the songs (well I do lip sync if that counts).
