Can you explain why despite putting this song, my post on Instagram got only 8 likes?

So in my previous post I mentioned how my new Instagram post where I posted my Sakleshpura trip pics got only 8 likes which is the lowest I got so far as my posts get 18 likes on average. I also used this super catchy song Can't Let Go by Faydee. Yeah my Instagram followers are mostly my real life peers about 21-27/28 age range and Indian too like me and I am 25 but still this song is so catchy in the chorus and has this cool modern vibe even if it's a 2014 song. But despite this it feels like many ignored my post and only 8 people liked it. I definitely feel with my sunglasses in some of the pics, I match the vibe of Faydee so yeah I expected more engagement not less. So hear is the song. Hear it and say how is it and whether I did the right thing by using this song for my post
