This is very relevant to me. There's a great song I heard on The Wire from HBO called "Analyze" by Sharpshooters [1]. Info on this group is almost non-existent; Only a brief synopsis repeated on Reddit and a few other sites. This was a song used on one of the most popular TV shows ever, I cannot imagine the amount of info being lost on lesser groups/songs.

Also related, I LOVE MF DOOM. Collecting his discography is a fun little task, considering he appears on various albums using one of many monikers.
