I thought this might be a good idea. If you have songs/demos or similar things that you have no idea who they are by/where they are from (era or album) then you could post it in here and someone might be able to help you out. Rather than having many a thread this could be one that we all look to? Example; "Who sings 'Don't Hold Your Breath?" "Keri Hilson sings a demo of the song in question, however Nicole Scherzinger is releasing the song in a new form". Good idea or a bit shit?
