Could make you think simlish is a real language, with words that do actually mean something more than just brabbeling around.
We should put some simlish lyrics next to the original song and look if we could translate some words out of it. With the more songs we do this, the higher the change will be we will eventually understand our little digital friends.
Sounds like an excelent job for you Metroman, cause I already am learning a third language. This is your change!
