Those inspiring works capturing tastes now and then (4-4)

'those inspiring' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'works capturing tastes now and then' is the wordplay.
'works' becomes 'muses' (I can't explain this - if you can you should give a lot more credence to this answer).
'capturing' indicates putting letters inside.
'now and then' indicates alternate letters (letters taken on a regular basis, now and then).
The alternate letters of 'tastes' are 'tse'.
'muses' placed around 'tse' is 'MUST-SEES'.

Can you help me to learn more?
