Would say this differs from boxset release to boxset release. There are some 3CD sets, even double discs, on the market, which I would clearly like to see represented in roon as a boxset with covers of the original releases, bonus discs or whatever.
A lot of double discs, and even some bigger ones, on the other hand, qualify rather as a very long playing album, hence a selection of tracks and compositions, with little chance for useful disc titles.
@mike i am maybe not the most representative classical music lover when it comes to boxsets, but I would love to see the disc no and disc cover ´stoppers´ within the tracklisting to disappear, particularly for compositions spanning over several discs, like operas and oratorios. Typical example of several operas:
Herbert von Karajan - Wagner: Der Ring des Nibelungen (CD version, that´s 4 operas on 14 discs)
4 acts of the first opera split into the first 2 discs but the “Disc 2” split is in the middle of act 3, apparently because there is a general tacet in the music. But that´s not useful information by any means when streaming or playing from local files.
That´s mainly an issue with CD boxsets containing one or more operas/oratorios, so I would welcome a feature deactivating boxset structure in the tracklisting only for those releases. If anything, an option to group several discs into one sub-release of the boxset (for those sets containing several operas, for example) might be helpful. In case of Karajan´s box, it is possible to retag it and use the 4disc digital download release which gets one the desired result in boxset view:
I don´t see the necessity to deactivate disc selector, even if it does not contain meaningful information on the specific disc.
For some pop/rock releases, particularly the ´Deluxe editions´ of a popular album, or some anthology boxes, I´d rather find it useful to split away specific tracks into one disc of their own. The latter might be useful for boxsets comprising of one or more albums plus one or more singles/EPs, i.e. releases which are not identical with discs, as several singles/EPs are oftentimes part of a general ´Bonus tracks´ disc. Examples:
Beatles - Rubber Soul (2026 blu-ray Deluxe)
The disc 2 contains not only sessions and demo tracks but also the single (2023 Atmos remix) which in my understanding should exist as a release in its own right. Interestingly, roon did not recognize the original album on disc 1 at all, but the wrong single on disc 2 if I leave out all the demo/session tracks in mono or stereo. If I add the complete disc 2, it gets messy, and the single disappears.
Again, I am in the camp of those appreciating new boxset features for quite a number of releases, so cannot really speak for those who have problems with wrongly re-identified sets.
