How to deal with meltdown toddler

Do you all reprimand and/or beat your child when LO is feeling cranky? Everything is also rejected except when feeding. LO will throw things around when upset intentionally. Keep asking me to change different youtube songs. I was firm when I declined his advances, but LO will start to cry/scream so loud that I got so frustrated. I will gently beat his palm when he throws things, and or his head when he tries to put everything into his mouth intentionally to test my reaction. Sigh.
