Beat and beat it, to the music (5)
I believe the answer is:
tango
'the music' is the definition.
(tango is a kind of music)
'beat and beat it' is the wordplay.
'beat' becomes 'tan' (tan can mean to beat or hit).
'and' means one lot of letters go next to another.
'beat it' becomes 'go'.
'tan'+'go'='TANGO'
'to' acts as a link.
(Other definitions for tango that I've seen before include "Dance; letter T" , "Modern ballroom dance" , "something seen in ballroom?" , "Dance originating in Argentina" , "Dance music" .)
