Hello Syrex, just wanted to check in cuz you popped up in my recommendation list! Fireflies is an amazing song by Adam Young, which I used to listen to back in the days, one of my favorites! Then, you bring us this wonderful cover/remix of the song, and you really brought the song back to life, and put a big smile to my lips :) ! You've made my day, thank you! Also u got +1 new sub! Much love
