What's your approach to expanding his collection - do you add cards based on what he gravitates toward, or do you intentionally introduce "bridge" artists to expand his palette?
Im not OP but i have a player for my kids which is basically the same. I do both. Sometimes I introduce songs and we talk about it, other times they hear something somewhere and ask me for it.
we'll see! probably both. for example, he likes Weezer's Blue Album, so I'll introduce him to Wowee Zowee next. I just want him to stay engaged.
