Festival dislikes including Queen covers (10)

I believe the answer is:

eiderdowns

I'm a little stuck... Click here to teach me more about this clue!

'covers' is the definition.
(I know this)

'festival dislikes including queen' is the wordplay.
'festival' becomes 'eid' (Muslim festival).
'dislikes' becomes 'downs' (I can't explain this - if you can you should believe this answer much more).
'including' indicates putting letters inside.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'eid'+'downs'='eiddowns'
'eiddowns' going around 'er' is 'EIDERDOWNS'.

Can you help me to learn more?
