If you like collecting FLACs, here's a good source if you are into the labels that they offer, basically you can subscribe to different labels and have access to FLACs of all their new releases. It is mostly indie electronica and rock, but they've been adding new labels every month or so. They have Sub-Pop, David Byrne's label Luaka Bop, and Ninja Tune, among others.
Each label subscription is $8-15 per month (some labels release more frequently than others). With most subscriptions, when you start, you get a certain amount of releases you can "unlock" from their back catalog and then you get everything moving forward.
It is the only service I know that offers anything like this.
My favorites are Ninja Tune and Ghostly.
