What would happen if I use other artistes' song(s)? I wish to know.

Gaps (which include singers) are a part of a system. Gaps don't exist for themselves, as such. Yet its the singer who can answer where its allegiance lies. Neutrality can exist, but that would imply any system can use or bargain; now that's a definition. Therefore, systems would want to be sure where that allegiance lies for security purposes. No system want an undefined road or way for its beings or people; no system want a weak channel.

All songs have a place they can take you to, but it could be an unproperly charted way. That is, a singer might be constructing but constructing without focus, just for momentary fun; whereas, a path is being initiated topsy-turvy. And a singer might be constructing with focus, still construction has its principles that should be obeyed; the singer might still be struggling with that. Then, there is the point where singing isn't just about opening a way, but can also shut a way (i.e. act as a Closure), or link two ways (i.e. act as a Jump). These have to be understood and known.

So, in all, the safety of using a way or a song, is in knowing which system it belongs to; because then the system, not necessarily the artiste, can render you access support. Thus, what would happen is about your safety. You could fall into a void or a storage and your safety would be in the hands of the system that owns the singer/song.

Furthermore, the above given points include religious singers too. Can you ascertain the God? If it's for God, then the system of God would render access support.
