To the listener, some lyrics are old-fashioned (5)

I believe the answer is:
early
'to' is the definition.
Both the answer and definition are adverbs.
Perhaps there's an association between them I don't understand?
'listener some lyrics are old-fashioned' is the wordplay.
'listener' becomes 'ear' (body part which hears or listens).
'some' suggests taking the first letters.
'are old fashioned' becomes 'y' (I can't explain this - if you can you should believe this answer much more).
The initial letter of 'lyrics' is 'l'.
'ear'+'l'+'y'='EARLY'
'the' is the link.
Can you help me to learn more?
(Other definitions for early that I've seen before include "Post this for Christmas?" , "Ahead of schedule" , "Opening" , "Premature" , "This bird gets the worm" .)
