Track Not Available- displaying every time on some tracks from Wild World by Bastille

[soawplays]

Trying to play my playlist but every time any of the following Bastille songs comes up, it displays the "This song is not available" message.:

"Warmth"

"Send Them Off!"

"Blame"

"Fake It"

"Way Beyond"

"Shame"
The weirdest part is that it's only these songs, nothing else. It started happening after I finished importing these same songs to my phone via iTunes, so that may have something to do with it, but I'm not sure why that affects it, as the mp3s weren't pulled from Spotify or anything. Really confused.

Edit: "Send Them Off!" and "Shame" have started working again, but no others have.
