Squeeze with bit of music that can give you the shakes (4,3)

'squeeze with bit of music that can give you the shakes' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'squeeze with bit of music' is the wordplay.
'squeeze with' becomes 'milk' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bit of music' becomes 'bar' (I've seen this in another clue).
'milk'+'bar'='MILK-BAR'
