What Qualifies As Christian Hip-hop?

Ah the good old days. I'm sure older people reading this might miss those days in Nigeria, when Independence Day celebrations were always looked forward to. From the parades, to the speeches, to the green-white-green dresses, to the my-country-is-the-best-in-the-world feeling. I've read about times like that, although right now, that feeling doesn't exist anymore. Independence Day is just like any regular day.
Remember the early days of CHH? There was this clear distinction between CHH and regular HH. The music  specifically targeted the Christian community, and if it was targeted at non-Christians, it was a clear salvation message.
A few years ago, maybe someone realized that method wasn't working. Like, Jesus commanded us to reach the unsaved didn't he? And there's massive joy in heaven when one sinner repents than the billions of other Christians already saved right? And that brilliant idea brought about the subtleness that is our reality today.
So what qualifies as Christian hip-hop? In Nigeria, there's this song that's just getting popular. Alert by Prinx Emmanuel. Does it sound like something maybe Lil' Kesh would sing? Or how about Moonwalk by 1K Phew? What if Phil Ade sang it?

What really qualifies as Christian hip-hop? Songs that have the name of God in it? I really don't see how this subtle strategy gets non-believers saved. After all, isn't that what this is all about? Well, it's the Holy Spirit doing the saving. He can get them saved through any means. It's up to him.
These days, artists like Snoop Dogg and Lil' Kesh put God's name in their songs too. Does that make them CHH artists? What qualifies as Christian hip-hop?
I guess what qualifies as Christian hip-hop is simple. Just a song by an artist that has allowed himself or herself to be used by God. It doesn't matter if the lyrics are direct or subtle. Or if it's something a secular artist could have sung. The most important thing is the fact that the artist is yielded to the Lord and God can actually work through his songs.
