Be the best in heavy metal (4)

Ross

I believe the answer is:

lead

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

This clue could be a double definition.

'be the best' is the first definition.
'lead' can be an answer for 'be' (leading is a kind of being). I'm not sure about the 'the best' bit.

'heavy metal' is the second definition.
(lead is a heavy metal)

'in' acts as a link.

Can you help me to learn more?

(Other definitions for lead that I've seen before include "Live" , "shot maybe" , "pioneer" , "Go ahead; element" , "Be ahead of - guide" .)
