There are semi-legitimate reasons to break Spotify's DRM. One artist I follow was about to release an album, but their record label cancelled it at the last second. Luckily, it still got uploaded to Spotify, so I was able to download a copy of it.
The albums are The Hands that Thieve by Streetlight Manifesto and The Hand that Thieves by Toh Kay, but I'm not sure if there's a detailed writeup anywhere. The band posted this: http://streetlightmanifesto.com/update-the-continued-struggl... and eventually had to cancel all of the preorders. They also posted this about their label: http://streetlightmanifesto.com/streetlight-manifesto-proudl...
