ragamuffins

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

'guttersnipes' is the definition.
I can't judge whether this defines the answer.

'music and cakes' is the wordplay.
'music' becomes 'raga' (I have seen 'Indian music' mean 'raga' so perhaps 'music' could also mean 'raga').
'and' is a charade indicator (letters next to each other).
'cakes' becomes 'muffins'.
'raga'+'muffins'='RAGAMUFFINS'

'for' acts as a link.

Can you help me to learn more?

(Another definition for ragamuffins that I've seen is " Urchins".)

I've seen this clue in The Everyman puzzle in The Observer.
