Worldly Songs

In my younger times, I love listening to love songs and OPM songs, I bought a lot of them especially when I liked the singer and their songs, then when I was baptized to be born again Christian, at church they play all Christian music which is really good, so as I attend church every Sunday, we do had praise and worship where all the songs are really great, now with 2 kids, I'm kinda careful of the songs that i played inside the house or at the car, I just felt that with this generation their music or lyrics it's so different. So what I usually play or listen to is all Christian songs, then one day as I picked my kids from school they start telling me about a songs sang by Katy perry. Elle told me that all of her classmates knew the lyrics except her, so I asked her does he felt bad? And she said NO.  do I feel bad about it? At first yes but now not anymore, you see the songs/lyrics before are so different from today, I know I can't control them forever, there will come a time that they will hear all this wordly songs, at least right now I can see that they can differentiate a good songs from bad songs, and I will continue to play all the Christian songs for them.
