You have already replied about the library. my question is different now.

Put the audio track in the main comp. Preliminarily you can prepare it in the montage program. https://www.youtube.com/watch?v=qvr9L4eA3P0

i have placed it in main comp. but its not syncing with the composition. neither beats not the effects. seems like you have slowed down music little bit or something i dont know

I can help edit the track for you.
