When you guys say "good SID tunes" you mean a quality, complex, well-made SID, correct?
I think, especially with the game-based SIDs early in the days of the C64 that there were a lot of
good melodies in poor SIDs that would be even better candidates for "remixing" than some of the very good SIDs of the latter days or currently.
Does that make sense? Take a SID like Cyberdragon. A recent tune, and a very well-crafted SID. I can see how people would say "where's the SID" if you remix that. Or Citadel tracks. Or how it would be hard NOT to do 1/1 on the flip side.
But then there are the simple, fun melodies in less sophisticated SIDs that could make for a great remix. Say Mail Order Monsters -

And then there are simple tunes like Spelunker - remixed only once by Gzilla some years ago, but I don't "hear" the SID at all...maybe just a fraction in it in there.
Compare the original -

Of course, there could be several schools of remix:
1. Remixing a great original SID that pushed the boundaries of SID music back in the day (Galway, etc) - or modern SIDs that are made with the help of modern technology and techniques that would have blown the minds of early Commodore bleep-blop-bzzz musicians (See: Telengard).
2. Remixing a catchy melody with potential from a lesser-known (except maybe to gamers who loved the game) SID. (M.U.L.E., some of the examples above)
3. 1/1 remake. Maybe something like Comets '97 by Chris Abbott from the Back in Time CD.
Or this:

4. "Inspired by" -- such as the Spelunker example above.
5. 1/1 remake with a spinoff - A good example outside of the C64 Remix community is the Ultima 5: Lazarus Soundtrack - which actually has some tunes from other Ultimas that C64 owners will recognize. Starts very true to the original, but goes off on a tangent and becomes a new tune. (:

Some really good ones in there if you like Ultima music.

I listen to it when I write fiction.

I guess what I'm getting at is that there are some "great SIDs" that were great only because of exposing us to a great melody, but usually when I've seen people discuss great SIDs they are talking about very impressive technical efforts (and of course good melodies to go with them - gotta have that).
Some of my favorite C64 melodies were actually quite awful SIDs!
And that's a pity because they don't get remixed much, or at all.
