Pet Peeve: "(Disc 1)" and "(Disc 2)". If you've got a two-disc CD, what's the point of attaching these notations to the album name? You get two albums that way, and there really isn't any need to split them. You can keep track of multiple discs using the Disc No. fields. I find it much easier to think of a multiple disc album as a whole.
I have even combined all 4 discs of a box set into one album, as essentially, it's one album split into pieces due to its size.
I have tagged discs separately if I felt there was some significance to the title. For example, John Lennon's box set has 4 discs, each with a different title.
Keeping the number of albums down will make your library cleaner and easier to handle.
