I have been a devout user of Apple’s iTunes software for quite some time now. Recently, I read somewhere about LastFM, an online radio service that customizes itself based upon your musical preferences.
The cool thing is that they have a plugin for iTunes that will report to LastFM what you have been listening to. Based on that information, they do several things. First, they build a playlist of tunes you can listen to from anywhere you can log into your account, tailored to your favorite artists. Second, they build a ‘neighborhood’ of other members that have similar tastes to you. You can listen to their personalized radio streams too.
In this capacity, I continue to find a lot of new music I enjoy. The LastFM service is more or less free (they ask for a donation after a 30 day trial). It’s definitely worth a checkin’.
