Invisible Circles by After Forever is a Concept Album centered on this theme, inspired by some of the children guitarist/vocalist Sander Gommans encountered during his previous job as an art teacher. In this story, the workaholic father refuses to compromise his chances at his dream career to help raise his daughter, leaving the mother to give up her job completely to spend time with the girl. This progresses for several years with the father rarely around and the mother taking out her frustrations on the daughter, who retreats into an escapist fantasy online in search of positive attention she doesn't get at home. But things go From Bad to Worse when an argument ends with the father walking out on both of them...
Not quite Played for Drama, but definitely present in "Amos Moses" by Jerry Reed. Amos' surly demeanor is explained by Amos's father using him to bait alligators while hunting when Amos was a child. This, err hands-on approach to gator hunting at one point cost Amos his entire left arm up to the elbow.
Although the parents in Tommy appear to mean well, they take Parental Neglect so far that it's a matter of opinion whether it amounts to this. Their attempts to cure their son include paying a gypsy to feed him acid. They are also known for leaving him alone with his abusive cousin and/or his drunk rapist uncle. According to Word of God re: an early interview with Pete Townshend, Tommy's dad hits him for being deaf, dumb and blind (never mind that his own actions—killing a man in front of Tommy and then forcing him to keep quiet—actually traumatized the poor kid enough to have caused these disabilities in the first place). While it's perhaps not intentional, the way both parents refer to him simply as "the boy" comes off as fairly sociopathic.
In the Evillous Chronicles, Duke Venomania, from the song of the same name, was locked in the basement for his deformity. It's also heavily implied in her song that Conchita's parents were also abusive. Not to...who am I kidding? Just about EVERYONE in the Evillous Chronicles either has abusive parents, or they are orphans.
TenThousandManiacs"What's the Matter Here?" addresses the issue of neighbors abusing their child, and the protagonist wanting to act, but not daring to intervene:
"If I'm the only witness to your madness offer me some words to balance out what I see and what I hear. All these cold and rude things that you do I suppose you do BECAUSE he belongs to you,and instead of love, and the feel of warmth you've given him these cuts and sores that don't heal with time or with age."
Skillet has a few songs reflecting Cooper's relationship with his father. He says his father wasn't physically abusive like "Open Wounds" suggests, but he was emotionally abusive. All of the songs involving Cooper's relationship were written and performed by him.
