Spotify Import for Hottest 100 includes Invalid Songs?

Hey Reddit,

I've noticed this before but can't quite understand why - I swear, for the last few years, including the H100 of Aussie Songs, the Spotify Song Import function can suggest songs which are invalid/not eligible!

e.g.

In previous H100's, I've been able to vote for 5 year old songs this way.

This seems to be an oversight, surely not something that is technically impossible - does anyone know anything?
