'lp presumably that's what dj might have done? 73'14' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'switched sides on' is the wordplay.
I cannot really understand how this works, but
'switched' could be 'changed' ('change' can be a synonym of 'switch') and 'changed' is found within the answer.
'on' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
