Island offering some music or fun (5)
I believe the answer is:
corfu
'island' is the definition.
(I've seen this before)
'some music or fun' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'CORFU' can be found hidden inside 'music or fun'.
'offering' acts as a link.
(Other definitions for corfu that I've seen before include "Ionian holiday island" , "Greek holiday island" , "Major holiday island off west coast of Greece" , "Greeks here?" , "Greek island, a British protectorate in C 19" .)
