I used Songbird from roughly when it came out and one of the features that I like was using mp3 blogs as playlists, then downloading the files I liked. I'm sure most of them are gone now unless I happen to still have a harddrive around from that time. But I found so much music that way. I'm not sure how I found the blogs now? Maybe that was when they would list the blogs they linked to on the side, or the blogs the author liked. I remember coming across communities of Andalusian punk, Finnish metal, Norwegian electronic music, and digitized Soviet rock/punk. Now I look back and wonder if those mp3s were there to download because streaming wasn't quite accessible enough. That was probably just a 2-4 year period I'm thinking of, maybe 2005~2009?
