'just typical' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'massage so dear mostly' is the wordplay.
'massage' is an anagram indicator.
'so'+'dear'+'mostly'='sodearmostly'
'sodearmostly' anagrammed gives 'SAME OLD STORY'.

'that's' acts as a link.
