Visually differentiate disks from the same album

Part of a list of smaller enhancements, which I think could help polish the app:

Visually differentiate disks from the same album

Currently, albums which contain more than one disk are shown as a single long list, as if part of one disk.

While dividing an album into one or more disks is sometimes just a vestige of physical CDs, it is still today a conscious artistic choice by many artists to divide an album into logical parts. To some users, separating disks is also an important visual cue to locate songs (e.g. first track of the second disk). Since Museeks doesn't display the track number next each tracks (which gives it a clean look), the distinction between disks is impossible.

This cue could be achieved by either

1. adding an empty space between disks of the same album, or
2. clearly labelling each disk as Disk 1 / Disk 2 / etc.

As an example, Apple Music labels each disk:

yep, this view deserves some polish, including shortcuts to play an album or shuffle a whole artist at once.
