Download track from opera with note from bank? (8)
I believe the answer is:
riparian
'from bank?' is the definition.
(riparian means relating to river banks)
'download track from opera with note' is the wordplay.
'download' becomes 'rip' (rip can mean to download or make a copy of).
'track from opera' becomes 'aria' (an aria is an operatic song).
'with' is a charade indicator (letters next to each other).
'note' becomes 'n' (abbreviation).
'rip'+'aria'+'n'='RIPARIAN'
(Other definitions for riparian that I've seen before include "Relating to a river bank" , "associated with banks" , "Relating to a riverbank - Iran pair (anag)" , "Relating to river banks" , "along river bank" .)
