FF5 is a Christian group from Georgia...Family Force 5, personally I fight them because I don't like them very much...I went to a concert they were at and they get all strange on stage
. But they do have good music. I'm sure she means Christian music...
I really like that song This Is My Desire. Its not the fastest song, but get an acoustic guitar and play with a group of friends in worship in english and polish...That song is wonderful, I really like singing it in polish.
