Cannot add two songs with same name by an artist to My Music

I am trying to add two songs with the same name by an artist to My Music but one doesn't add to My Music because iTunes appears to believe it's a duplicate I do not need, however this is frustrating as it means I can't add both EP & Album versions which sometimes differentiate.

My example is a song called Shallow by Beach Fossils, the EP version (on Shallow) is different to the album version (on Clash The Truth) & so I want both.

Is it possible to force it to add it to My Music? I haven't tried but assume you can add two versions to playlists, this is no use though as I want both in My Music section.
