Sorry, I but don't see your problem; this is the way it is designed and supposed to work; Songs is a list of all the pieces known about my MS
It sounds as though you want to call it something else so you can use the word "Songs" for your own purpose. If this was possible, it would make life very difficult for people trying to support you because the accepted meaning for Songs would be different from yours.

Just put the songs you want in a collection called  "Some Songs"   (replace "Some Song" with something showing what it contains)
Put your notes in a collection called "Some Song Notes" or whatever
Select the collections(s) you are interested using the filter; this will restrict the songs to collections chosen by the filter. Although you are not trying to do this here, can also select any song that contains specific text in it's filename or metadata (but not based on the contents shown on the song page)

A collection can be sorted in A-Z to ease jumping around and/or scrolling

On reflection, does Mike offer a library setting to use "piece" when refering to a song; this chnage the Songs tab to Pieces, I believe that this was implemented for users who wanted to call all their songs "Pieces" whereas it sounds that you want to use both forms of the name. Still, might be worth giving it a try to see if it does what you want.

I found this. It will spare me confusion so I'm pretty pleased with how setting it all up is going now.
Thanks
