My phone will play random music, sometimes with no apps running

[Android Central Question]

So I have a decently new Moto E4 (not plus) and have had it for about a year now.
Recently it started playing this almost rock/pop little tune for about a minute straight, no words, just a byte track of sounds. I don't think it's malware but it will play sometimes when I open apps like mobile games or communication apps; sometimes with nothing open at all.

Please let me know if you have any solution to this problem, or if you have the same problem too!
