Baby(ies)'s response to music

Hi. Do your baby(ies) respond to music you listen to? When was the first time? I'm FTM, currently 19 weeks pregnant with twins and I feel they (or one of them I'm not sure) move when I listen to music, but only the drums part. It always happens that way. Is it the real movement or is it just me? Not trying to compare one baby to another / one pregnancy to another.. I'm just trying to figure out what happened 😊 thanks!
