What's the best (preferably free or with available means of unlocking) music organizer? I never really had to worry about it because I always just wanted full albums and everything was easily organized into Artist\Album\Song instantly because I would only rip or download full albums (with the occasional single from iTunes, but that's easy to place.) I then started only keeping music on my iPod and deleting the file once it was transfered, and I would just listen to music off my iPod on my computer which made things simple. Now that I'm getting in to DJing I'm downloading a lot of singles (I have a subscription service where I can download however much I want for a month, and most of the songs come with the original file, the remix if available, possibly a clean and explicit version, an instrumental, and acapella. This creates a problem since I wouldn't just listen to say the instrumental on my iPod so I don't want to store everything there, so I figure I should have it on my external hdd. I just don't want to manually organize them since some even have different naming conventions. suggestions?
