I dislike a few things about Spotify. 1. Unsustainable financially. They're losing money and will likely have to change the service or charge significantly more at some point. 2. Occasionally it doesn't have a song. Too obscure, too new, or some kind of legal wrangling is preventing it. Spotify doesn't have a good solution in this case. I can't augment it with music in my own collection. 3. With Spotify you have a huge music collection, but it's not portable. If they change the service (see #1) or you want to use a different client, you don't have options. 4. Mobile apps are limited to 96kbps. I want to be able to connect my phone to my (or a friend's) stereo to play music in the living room. The artificial bitrate limit means that won't sound good. These might all be things only nerds care about, which is why I don't expect the market for my side project to be particularly large. But it's enough to make me want an alternative.
