Is music from the band Flyleaf religious?

Flyleaf talks about God and Jesus. Most of their songs are about God or Jesus.

The lead singer, Lacey Mosely, used to be on drugs and almost attempted suicide until she was touched by God. She said, "I scream in my music because Gods voice can be loud and over whelming maybe even a little frightening, but we have to hear it."

Here are a few Flyleaf songs that have a religious meaning:

• The song 'I'm So Sick' is about how life is filled with bad things and wanting God to take it all away and wanting a pure life.
• In the song 'Cassie' is about two girls, Cassie and Rachel, who were shot and killed because they were asked "do you believe in God?" and they said yes.
• All Around Me is about how God is always with you and will protect you.

  The song Perfect is about how you try to be perfect but can't, and want God to take you in his arms and remind you that nobody is perfect and God will love you no matter what.

• There For You is about how God is always there for you but you never there for God.
• Beautiful Bride talks about the body of Christ. (beautiful bride/body of Christ)

  Although all the members are Christian, Lacey has stated it isn't a Christian band.
