Although I find Spotify immensely convenient, I occasionally read that music streaming services like Spotify has small payouts to artists. With new solutions like Cloud Player, where one can stream files from e.g. Dropbox, I wonder if it might be a just-as-convenient solution in many ways to buy songs and albums and host them via Dropbox. And I might end up saving money over time, since the cost of the music that I actually listen to might be less than the subscription fees to Spotify.
My question is then: Which digital medium should I choose to maximize artists' profits?
