Song not playable on album

[Caface]

I'm trying to listen to the song 'My Rollercoaster' on the album 'Remember That I Love You' by Kimya Dawson. Often the song isn't even present on the album, but when I do find it, it's grayed out and won't play or open. The only available variation is the vastly reduced movie soundtrack version. Anybody know what's going on here? It's a song that means a lot to me, and it's really disappointing/frustrating that it's the only one of her songs that I can't listen to.
