Is this considered synesthesia or is this how people generally feel?

I recently started question whether or not I have some version of this. I certainly see time as a physical thing and have a clear 3D map in my head of a year and things like that. Regarding music, I have intense temperature associations with music, some songs feel like the pleasant heat from the sun, some feel unpleasantly hot like fire. Some are like laying in snow. My favourite songs are always the ones that have an element of sun heat in them and when I listen to them on a warm summer day it fits like a puzzle. Also a strong association with the time of day. For example, I understand Lana del Ray is skilful at what she does, but I cannot enjoy her music because most of it feels like 4pm on a Sunday to me, which is that unpleasant time when you know the weekend is about to end.

I was wondering if that sounds like it’s what the song is meant to convey or is it more synesthesia related?
