I'm not sure if this has been already suggested.

Is it possible to have sub-fields for "Medley" tracks.

Presently a medley may appear like this:

Devil With The Blue Dress Medley: Devil With The Blue Dress On/Good Golly, Miss Molly/Jenny Take A Ride

Composer:Robert Alexander Blackwell ("Bumps" Blackwell)/Bob Crewe/Enotris Johnson/Fredrick Long/John Marascalco/Richard Wayne Penniman/William "Mickey" Stevenson

What I would like to have is this:

Devil With The Blue Dress Medley
a) Devil With The Blue Dress on Composer: Fredrick Long/William "Mickey" Stevenson
b) Good Golly Miss Molly Composer: Robert Alexander Blackwell /John Marascalco
c) Jenny Take A Ride Composer: Bob Crewe / Enotris Johnson / Little Richard

This could also work out to split hidden tracks.
