They teased us at first, but it does seem that iTunes "inspired" music player Songbird is now available for the Mac as a nightly build (read: use at your own peril). Built on the same guts as Flock, I'm eager to see what comes of this, though it really seems like Pandora is doing more to revolutionize music listening thus far (don't miss Airfoil + PandoraMan for the best wireless listening experience). Oh, and with other apps that add intelligence to your listening habits and enhance your playlists (see Last.fm, MusicIP, beaTunes and Soundflavor) the landscape in music consumption habits is surely going to change drastically in the next year. I'd love more than anything for Songbird to take a lead in that respect, but to do that, I think it needs to focus on the experience of listening to music, period; it needs to define what the Songbird listening experience is, and be able to answer clearly and concisely why anyone should care. It's not just that it has a browser built in or that you can buy from 8,000 different music providers. I don't care about any of that -- I do care, however, about how good the music coming out of my speakers is and how much the tool I'm using to play that music has to do with it. The future's not in featureware, it's in experience.
