I became lucid because I was singing a song in my head. New way to become lucid ?

Title. I tried to DEILD last night, and after like 5 minutes of nothing happening while recalling my previous dream, I gave up and began to sing a song in my head, then I felt the sleep paralysis I have when I try to DEILD, the song was still there in my head though, then the transition began and I got in my dream and the song faded away, I jumped everywhere in my dream of joy and woke up.
