I keep everything in the main library Artist/Album/etc. Reason being, the software we used at the time was playlist and script driven. So you'd have something like: 'play 5 songs from the top 50 set list - play 3 songs from the commercial set list - play bumper and station id - play shoutout from random Indie band - play 5 from secondary set list - etc. So, at the time it didn't make sense for me to segregate the Indie from the commercial. We played commercial cuts obviously for those familiar with them, but introduced Indie bands and promoted them for the most part. It was a shit load of fun really. Then the RIAA screwed everything up levying fees on internet radio that weren't even required for terra radio. We had to pay $.5 per song, per listener, which doesn't seem like a lot but when you figure up how many 3:00 minute songs fit into an hour and you have several thousand people tuned in daily from all over the world, it started to become some real money. Then we went to Washington to plead our case in front of a commission headed up by Senator Leahy. In the end a lot of us disbanded because we were doing this as a work of love for music and the Indie bands, and just couldn't cut the fees on top of ASCAP/SESAC/SOCAN/BMI licensing. It was fun for a while tho. I've had a lifelong love affair with music.

ETA: At one point I really got into it with my postal carrier because he was toting sacks of CDs. I had to put a special box at the mailbox so he could dump all the CDs in. LOL
