Group tag

[simoncn]

For this situation, you should be using some other tag such as Work.

When tracks are combined as a Group, these tracks are played together and consecutively. These tracks are part of an album or disc and playing the album or disc containing these tracks should play the tracks in the order desired by the performer (interspersed with other pieces). Using a Group would contradict the performer's intention because it changes the playing order.

Using a Work is preferable because this doesn't prevent the tracks from being played in the correct order as part of the disc or album. The tracks that make up the Work can also be viewed and played consecutively if desired.
