Time to describe emotions that I don't know the word for:

A song comes on and it's so good you put it on repeat until it no longer makes you want to cry, laugh, scream, and sleep at the same time. It makes you feel incomplete because it's so perfect and unreachable. (E.g. Because I'm Me by The Avalanches)

Or

A song comes on and it's just right. You can play it on repeat without the overwhelming feeling of perfection.
It's a lukewarm melody. (E.g. With You by Cathedrals)

Note: My examples are subjective and are just songs that made me feel these emotions.
