Why did Crystal Castles remove some of their songs and added new alternative ones?

[brokemono]

When I looked at my playlist some time ago I saw that their song "Deicide" was removed/unplayable for whatever reason. After some time listening to random songs their new/alternative songs came up so for example instead of "Deicide" now there is "Their Kindness is Charade", they sound similar but are not the same.

They did add some cool songs in too that I haven't heard of before, that's nice, but why remove the others, huh?

I wanna know what's up with that, and when will they bring the other ones back because I liked those, they were in my playlist that I listen to when I work. Not cool.

I don't wanna listen to it on YouTube, I have premium here, I wanna hear it here.

Does anyone know what happened?

So yeah it's not Spotify's fault this happened, Ethan Kath or someone who is able to could just change available stores and stuff like this. Just contact Ethan Kath and tell him to restore the track. XD
