Why does the iPhone split music albums into a bunch of 1 track albums?

Question

iPhone

Everything is correctly indicated in the tags, the name of the album is the same for everyone, the name of the CD is the same, the track numbers are affixed (neither 1-12 nor 01-12 helps). Apparently due to the fact that each track has a separate artist, itunes breaks them up. What else can be done? I really don't want to overwrite the names of the performers, although it helps.

Answer 1

Because damn iTunes! Put a checkmark "Part of the collection" on all compositions.

Answer 2

The reason is that there is an Album Artist and just an Artist, in the collections in the Album Artist field you need to enter: Various Artists, and in the Artist field there is already the name of the artist, and you can not check the box.
