If you like music with a “hard” or “strong” feel but you want it to a) have a purpose and b) fit with your Christian beliefs, check out:
“The River” by Decyfer Down from the Album Anthology
It’s about Baptism and how we should have known from the start that we were not created to walk thru this life alone.
It’s about Redemption from a sinful world and Redemption from the choices that we know we should not make but continue to make.
Even if you don’t consider yourself a Christian, its still a great song if you like the up tempo, “rock” type of music.
Take a listen.
