Do you ever pine for the days when listening to the radio was a great experience? The days of knowledgeable DJs who really knew what they were talking about? DJs who had passion for the music they were playing and knew about the musicians and their influences? When bands would come on the radio and discuss their songs and what they mean? Those days may be gone for terrestrial radio, but a new Music 2.0 service called SpotDJ is taking the concept to the next level.

SpotDJ is a web site and downloadable application that delivers a unique radio DJ style experience to iTunes playback. Members of the SpotDJ community record their own audio spots based on individual songs and artists. After listening to a song in iTunes, instead of going directly to the next song, you hear a relevant spot about the song or artist you just heard (assuming a spot exists in the database). For instance, I decided to listen to some Dandy Warhols today to test out the service. After the first song finished playing, I was very surprised to find out that Courtney Taylor-Taylor himself recorded a spot about his favorite songs. As I listened to more songs there were more spots by Courtney about touring, how the band got their name, and his influences. How cool is that? As another test, I listened to the Beastie Boys Paul’s Boutique. Sure enough after each song, I got spots that discussed the individual songs, the band and where all the samples came from.

If there is no spot for a specific song, SpotDJ will see if there is a spot for the artist. If there is neither you wont hear a spot. Once all spots for a particular artist have been heard, the system is smart enough to know not to play them again. Want the experience on the go? SpotDJ can also attach spots to playlists on your iPod. You also have the ability to comment on individual spots, send member messages and email/embed spots. So there’s no spot for your favorite song? SpotDJ provides a variety of methods to record your own spots - via microphone, uploading an mp3 and even via phone.

Aside from some needed UI tweaks, SpotDJ is hands-down one of the coolest Music 2.0 services I have ever seen.
