The amount of sin that a song mentions is irrelevant? Even if it portrays it in a positive light? I think it is sad that you feel that way. Have you ever stopped to think what the Lord's opinion is on the matter? In the end...our opinions are irrelevant. It is what the Lord says that matters. I've posted some verses for you. Please review them and think on these things.
"Her priests have done violence to my law and have profaned my holy things. They have made no distinction between the holy and the common, neither have they taught the difference between the unclean and the clean, and they have disregarded my Sabbaths, so that I am profaned among them."
Ezekiel 22:26
"Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him."
1John 2:15
"Pure and undefiled religion in the sight of our God and Father is this: to visit orphans and widows in their distress, and to keep oneself unstained by the world."
James 1:27
