The bug
Note blocks placed on raw metal blocks all play the bass drum sound. This might be intended as they could be considered ores, but I made this report just to make sure. Since the raw metal blocks not making the same sounds as their metal counterparts is considered a bug (MC-223153, MC-223331), I would expect that note blocks placed on those blocks played the same sounds as the metal blocks.

Raw "metals" are minerals, no metals. To get the metal you must smelt the items in a (blast) furnace.
So I think is correct that the sound is like a mineral (stone), not a metal.
