Tracker not on Spotify

[Marnix]

Does any one knows the reason why Tracker is not on Spotify.
There is only an album sampler with 4 songs (Beryl, Basel, Where I Go & Broken Bones).
All the other Knopfler albums can be found there and even all the film stuff.

Killl to Get Crimson and Metroland are missing too, must be a record company thing. Possibly they want people to buy Tracker now and they'll put it online later on.
