Wrong. Songs with "#am4" can be inserted with AMK. In fact, the addmusic specifier is a feature from AMK, not AM4 (and neither AMM) and tells AMK to emulate AM4 or AMM. Specifically, if you try to insert this song with AM4 (or AMM if unsampled) you'll get an error because AM4 can't recognise the #am4 tag (and neither "#samples" because that again is an AMK feature).
Furthermore, the only addmusic we have in the tools section is AddmusicK so why should we host songs which can't be inserted the only addmusic we host anyway?
But yeah, the rest is mostly correctly. One thing you could have mentioned is that BRR samples are often put in their own folder which means you need to copy the whole sample folder (not just the samples themselves) into samples but the procedure is similar (if not, they simply belong to the samples folder). Also, the music list only updates if you reload the ROM.
