Music linked to board book from Dr Seuss (3,2,3)

I believe the answer is:

hop on pop

I'm a little stuck... Click here to teach me more about this clue!

'book from dr seuss' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'music linked to board' is the wordplay.
'music' becomes 'pop' (pop music).
'linked to' is a charade indicator (letters next to each other).
'board' becomes 'hopon' (I've seen this in another clue).
'pop' after 'hopon' is 'HOP ON POP'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
