'celebrated beauty releasing hard' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'rock song by the 2s' is the wordplay.
I cannot really see how this works, but
'rock' could be 'ore' (ores are found in rocks) and 'ore' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
