Record part of poem in lounge (7)
I believe the answer is:
recline
'lounge' is the definition.
(both can mean to laze around)
'record part of poem' is the wordplay.
'record' becomes 'rec' (I've seen this before).
'part of poem' becomes 'line' (poems typically have several lines).
'rec'+'line'='RECLINE'
'in' is the link.
(Other definitions for recline that I've seen before include "Lie on the back or side" , "Lounge" , "Lean back, relax" , "Lie back and take it easy" , "sit back ..." .)
