'classic albums often are' is the definition.
I can't tell whether this definition defines the answer.

'about to get streamed freely' is the wordplay.
'about to get' becomes 're' (I've seen this in other clues).
'freely' indicates an anagram.
'streamed' with letters rearranged gives 'mastered'.
're'+'mastered'='REMASTERED'

'as' is the link.
