Ok, I don't know track times, but I do know that there are a few new tracks not on the DL 6 disc set, and there are a few revisions.
Here's what's new or different on the DL "Remember the Moments" CD's.
Disneyland:
1. New Main Street Track "Beautiful Beulah".
2. The Splash Mountain Medley now contains the correct "Burrows Lament" section.
3. New "Sooner or Later" Critter Country area music
4. "Welcome to Tomorrowland" is totally new. I'm unclear on where at Disneyland it plays, since it was also included on WDW's new OA.
5. "Honey I Shrunk the Audience" is new, but also on the WDW OA.
6. The Space Mountain track is the full version, so it's longer and has the lift hills, and some exit music.
California Adventure:
7. A Bug's Life Suite is completely new (A Bug's Land area music).
8. "Monsters Inc. Mike & Sully to the Rescue" is totally new as well.
So, that's it, and to me, it's worth picking up the new CD set, even just for the correct versions of Splash and Space Mountain.
