Id3 Tags not properly recognised

I have so far tried a number of applications to listen to music on my Android phone, and I'm for now settled with Google's Play Music. However, it has the same issue of every other app I've tried. Let me try to explain with a real issue: I've got Anouk's Together Alone album. All the songs have the same album tags. However, Play Music likes to show 2+7 songs (9 songs in album) as 2 different albums, as seen in the below screenshot. How do I fix that?
