Shelves part of LP and the songs on it? (10)
I believe the answer is:
sidetracks
'shelves' is the definition.
(both can mean to divert from an original plan)
'part of lp and the songs on it?' is the wordplay.
'part of lp' becomes 'side' (A-side or B-side of a record).
'and' is a charade indicator (letters next to each other).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'songs' becomes 'racks' (I can't justify this - if you can you should believe this answer much more).
'on it?' says to put letters next to each other.
'side'+'t'+'racks'='SIDETRACKS'
(Another definition for sidetracks that I've seen is " Diverts".)
