Curious if anyone has the same problem as me!

Hey, im actually a pretty good singer, but my problem is that i cant hear when to start singing to an intrumental or karaoke text without a helping line. Its like i cant feel the music. I know im not tone deaf, since i took a test and i got 97% correct. I guess most people hear the words inside their head, when hearing the intrumental of the song, but that just dosent happend for me;(((

So does anyone else of you have it? And is it a word for it? because i cant seem to find anything of it on the internett.

thank you for your answers)
