Yes, that is definitely happened to me. Sometimes the song will get stuck in my head all day and I won’t understand it since I hadn’t heard it in a while lol I love your singing voice as well! That was really cool.

Actually, this song comes from a classical Russian opera: Prince Igor - by Alexander Borodin. The song title says, fly away on the wings of the wind. It’s a kind of dreamy song about sense of freedom.

I don't know what that song is that you were singing but it seems slightly familiar and like maybe I should know it. Yeah, I think everyone has songs that pop into their heads, most of the time I think they are just earworm songs

I've not heard the original version of that song before. I've heard variations of it though.
