One of the "strategies" I've read about for indie releases is to find a blog or podcast or review site or musically related site and offer them exclusive access to your album for a period of time. The idea is that it will generate interest, or at least be exposed to a new audience. Although it is different in that anyone going to that site or listening to that podcast can listen whereas on spotify you'd have to pay in order to gain that access. While I doubt many people subscribe to spotify just for a tweedy album (but who knows) it worked in as much as we are talking about it now.
