Bullocks, this happened right after the artists EODM (Eagles of Death Metal) and Eagles of Deatm Metal were merged, quite a coincidence isn't it.
Additionally, the song "I Got a Feelin (Just Nineteen)" is still available, whereas the remaining part of the album is not.
I am about to give up on Spotify for this particular reason, you can keep contacting customer service all you want, but corrupted (ie songs skipping or stopping suddenly) or missing content won't be fixed at all.
On further investigation using Christoffer's availability tool, the entire album is available in the US, whereas the song I Got a Feelin (Just Nineteen) is available to the rest of the world. Which sounds like a mistake rather than a licensing issue.
I'm finding this really annoying, every other EODM album is available on Spotify, just not this one (I'm in UK) - however, the album is available on Amazon Music for streaming as i have it on there. Trouble is, I want all my music in one place, I can't add any DBS tracks to a playlist, if I want to listen to the album, I have to physically switch to Amazon Music - which I can't do if I'm driving!!
