Maybe a forum page with a thread for each song (as it comes up) and keep all questions, answers, "must listen" version list, etc - that could keep it in an organized place while we gather the data together. Could just edit the main post so all the information we have for a song will stay at the top.
Tag the front of the thread [Original] or [Cover] stuff like that could help organization and being more searchable as well
Could make a dedicated section for it. Then could link to those pages from the song page in the spaffbase.
Not a bad idea. Let's get some upvotes!
