My dilemma consists of two songs, both of which run in Bearshare searches for hours at a time with no hits. Keeper of the Light by Warren Nelson, and Einstein the Genius by Cranberry Lake Jug Band. Both are played by MPR quite often, but I can't find myself copies of either tune.
However, thanks to the internet, I'm now listening to You Are The Woman by Firefall. This song has been stuck in my head literally decades, since before I can remember (the earliest memory was in a dream, when I was 5 or 6, so I must have heard it before then). It came on the muzak at work, I punched a few lyrics into Google, and I had the performer & song name. Bearshare came through on that one, thankfully, otherwise it'd still be boring deep within my skull, virally replacing important memories with it's catchy lyrics.
