i got rhythm

I'm a little stuck... Click here to teach me more about this clue!

'song that' is the definition.
The definition suggests a singular noun which matches the answer.

'mighty thor dancing' is the wordplay.
'dancing' indicates anagramming the letters.
'mighty'+'thor'='mightythor'
'mightythor' is an anagram of 'I GOT RHYTHM'.

'gets' is the link.

Can you help me to learn more?
