But the richest bands don't guarantee high quality music. In fact, as mainstream music suggests, often it's the contrary. Similar situation with low budget vs. high budget movies.
Our algorithm, much like Adwords, will be a combination of ratings, relevancy to a particular user, and only after those things help determine a fit would their bid affect anything. Also, a band who spends more may be introduced to more people, but will not necessarily saturate the experience for a single user, as is the case in regular radio. Also, we don't sell pipe dreams to artists with low quality material. Everybody has to be approved, and I think you'll find that even if you don't love everything you hear on Earbits, it is all high quality, professional-grade music.
