Is it normal to get addicted to sounds/phrases

My mind feels like a parakeet in this way. Does anyone else get this, it's like when a song is stuck in your head, except with spoken phrases and/or noises from videos instead. I listen to them how some people listen to music. I'll just have stuff like the same tutorials, Youtube poops etc. that I've watched playing in the background while I do other stuff. Some I've watched 100s of times so I know all the words, I just really like the way they sound. IIN?
