How do you kinfirm a song (musickin/songkin)

Not exactly fictionkin related, but since I've seen quite a few songkins on here...

how do you kinfirm a song? I'm kinsidering one rn and I've been doing so for the past 2-3 weeks. i feel a strong connection to it, but I don't exactly relate to it. I mean, I kinda do since one of my kins is affiliated with said song, but other than that I don't think that that's why I'm kinsidering the song. to put it short, I feel a connection to it in an alterhuman way, not in a way that I simply relate

also bonus question, if you're a songkin/musickin, do you get kinshifts? if so, how do they feel like?

Anyways I think it's a kinfirm but I wanna be sure, thanks if any1 responds ok bye explodes
