Motown star is good? Indeed! (4)

I believe the answer is:

gaye

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

'motown star' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'good? indeed' is the wordplay.
'good?' becomes 'g' (abbreviation).
'indeed' becomes 'aye' (I've seen this before).
'g'+'aye'='GAYE'

'is' acts as a link.

Can you help me to learn more?

I've seen this clue in The Guardian.
