What's up with album's mindless followers? (5)
I believe the answer is:
sheep
'mindless followers?' is the definition.
(sheep can mean an unquestioning follower)
'what's up with album's' is the wordplay.
'what's' becomes 'eh's' (sound used to ask 'what?' or 'pardon?').
'up' is a reversal indicator (in down clue: letters go upwards).
'with' means one lot of letters go next to another.
'album's' becomes 'ep' (I can't justify this - if you can you should believe this answer much more).
'ehs' backwards is 'she'.
'she'+'ep'='SHEEP'
Can you help me to learn more?
(Other definitions for sheep that I've seen before include "Cotswolds?" , "- may safely graze (Bach)" , "feature of 21/23 [NATIVITY SCENE]" , "Ewe" , "Woolly quadruped" .)
