`getTrack` returns invalid Track object whereas `getTracks` works as expected

[wiencheck]

When using Spartan method getTrack(id: String...) Track object is received but most of its properties are nil, when I checked the uri of the object it turns out that actually an Album object was received but when Spartan tried to map it to Track most of the properties were nil.

See the Xcode Quicklook of the object

You can see that the object is in fact an album.
I think I'm calling the method correctly

Although this method gives wrong results, using getTracks(ids: [String]...) works correctly and I'll be using it to get single tracks from the API
