'songs' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'most excited about alien' is the wordplay.
'excited' is an anagram indicator.
'about' indicates putting letters inside.
'alien' becomes 'et' (extraterrestrial).
'most' anagrammed gives 'mots'.
'mots' going around 'et' is 'MOTETS'.
