Miss album? A demo I sell excitingly covers it (12)
I believe the answer is:
mademoiselle
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'miss album? a demo i sell excitingly covers' is the wordplay.
'covers' says the answer is hidden in the clue (I've seen 'covered' mean this (the answer is covered up by the clue)).
'MADEMOISELLE' is hidden within 'miss album a demo i sell excitingly'.
Can you help me to learn more?
(Other definitions for mademoiselle that I've seen before include "Young lady" , "Foreign woman" , "French miss" , "Young Frenchwoman" , "French girl; governess" .)
