The toddler I'm taking care of sometimes already came with a pre-installed musical taste. Unfortunately a lot of Disney and Musical stuff. We usually agree on a mixed playlist - some of his, some of mine. Not a problem, they have the right to their own taste, even if it's crap! I remember my dad being a bit of a muscial guide, but also something of a 'music police' when I was a kid, and as a result I did develop a large and interesting musical taste but also became socially awkward and missed the entire development of electronic music ... And I secretly like the veeery long song with the small red tractor feeding all the animals, it's kind of catchy - the new Schnappi even, who knows!

My own child, already grown(ish), who was exposed to pretty much the entire musical spectrum is now into electronic stuff. He has a little box full of buttons he presses to produce peculiar loops and sounds, anything from 5-dimensional farting to voices of anatomically correct angels. It was a gift from his former 'electronic music is of the devil' grandpa, hehe.

ROCK a bye baby per chance??
