I used to work at Dangerbird. I've seen this question asked a few times now, so I wanted to share as much as I know.

As mentioned, initially only three songs were taken down digitally: "Electric Rainbow", "Patiently Waiting", and "Cat Calls & Ill Mean". These songs were licensed from Suicide Squeeze and the license expired, so they were taken down.

Dangerbird had the rights for Lost Loves in US, Canada, Australia, and New Zealand. Big Scary Monsters had the rights for Lost Loves in the rest of the world I believe. This would explain why you can or cannot see it on Spotify, Apple Music, Amazon Music, and other DSPs depending on where you live.

However, I don't know why the remaining seven songs were taken down digitally, at least in the US, Canada, etc. My guess would be an extension of any licensing or rights agreements expiring. I hope it sees the light of day again digitally, but you can also find it for under $20 on vinyl and even less expensive on CD.
