Music has two very important faculties, finding it and listening to it. Most services offer one or the other, but never both.

Genius Mixes, not playlists, can serve both needs. Backed by the iTunes Stores profitability, an online version of Genius Mixes can afford to be commercial free, unlimited in play count, and unlimited in skip count.

iTunes can easily cross pollinate a preset number of stations catered to your tastes with songs sourced from your library, and songs recommended to you by the iTunes Store.

Listening and discovering deserve equal footing with any musical service.
