This might interest some of the people here:

NES Music Archive just got updated:

* All new rips and fixes from the last year or so

* [NEW FEATURE] Release date format switched from YYYY to YYYY-MM-DD format where available.

* [NEW FEATURE] Prototype sets moved into a separate directory.

FYI, Gyromite in that archive is actually Stack-Up (Stack-Up is Stack-Up too). This has been mixed up in several online collections for a while. Zophar's actually has an NSF of Gyromite on their site, but I can't say whether it's completely good or if it needs some fixes.

ETA: M.U.S.C.L.E. - Tag Team Match is missing the Title music. I don't know if the Famicom version uses different title music than the USA NES version, but the title theme from the USA NES version isn't in either of the NSFs in the archive.
