How do i find the name of song?

I wanted to have some traps in my game be timed to the music.

What's the most effective method to do this?

I would suggest you use a software like FreeTar Editor to generate an array that'll control your traps. You can use one channel for each trap pattern, so, for instance, if a trap goes on with the drums, just mark the drums on a channel and if another trap goes with the vocals, just mark its channel according to the vocals.

Hope this helps.

Cheers!
