Why are some songs marked as "ADHD"? This sounds like a medical claim that you should not be making.
Besides, does it count as a medical claim if certain content metadata tags happen to coincide with medical acronyms? I'm not a regulatory official, but this seems like a grey area _at worst._ no diagnosis is being made or even implied.
That said - regardless of regulations, you don't want to confuse your users, so better leave this acronym out indeed.

You're going to have to explain that one.
