And option 3:
Not complicated at all. But first you should understand that MB is a music -manager- first. And then a music player. If your albums aren't tagged properly you'll get issues such as you're experiencing.
An album requires consistent tags. All the tags from each album, with the exception of the track title, should be the same. Artist, album artist, album title, and year should be the same. If the album is a compilation, with a number of different artists, make sure album artist is Various Artists, or something similar. When album artist is missing, MB assumes the artist is the album artist. Which would result in the tracks from one album looking like they're from a number of albums.
