Support disc subtitle tags

[alessandrococco]

Description

Hi @OxygenCobalt, thanks for Auxio, it's an awesome app!

---

I have some multi-CD albums where each CD has a title, e.g.:

(this is Lollypop on Linux)

The tag is DISCSUBTITLE:

Could Auxio show the DISCSUBTITLE (if available) next to (or instead of) Disc X?

Oh, that's neat. I can do this (always willing to add new metadata support), but:

1. What's the ID3v2 analogue for this? In vorbis you can do DISCSUBTITLE, but in ID3v2 I'm not quite sure. I'd imagine TSST (Set subtitle) would work here.
2. Would you like it formatted like Disc 1: [subtitle] or just [subtitle]?

[alessandrococco]

Great, thank you!

1. Yes, it should be TSST
2. Uhm, maybe the disc number should remain. What about [subtitle]\nDisc N? E.g.
   The Supernal Clear Light of the Void (smaller) Disc 3

[OxygenCobalt]

Okay, I'll either go with your proposed style or my style, depends on which one looks better. This isn't likely to make it into the next release, but definitely the one after.

while it is not directly related to this issue, could you make items tagged as "disc 0" show up as such? this would be useful for separating classical works, where an overture might not be part of any of the acts, and other apps allow it too.

[OxygenCobalt]

The issue is that a disc number of "zero" may refer to a legitimate pre-lude such as in your case, or that there is no disc value whatsoever. The latter is common in older files that want to maintain consistent tag sizes and thus reduced I/O work.

How about this: If a zeroed disc has a subtitle value, it will be shown. Otherwise, it will be ignored. What do you think @illdeletethis?

imo good idea. for style, i think
Disc 2: The Supernal Clear Light of the Void
could work

[OxygenCobalt]

Good idea @KraXen72. Albeit, to retain consistency I might actually do something like:

Disc 2 (Bright Font) The Supernal Clear Light of the Void (Dimmer Font)

Sort of like how song text is structured.

Another thing: I'll probably add a special shortcut alongside this that will allow you to play and enqueue individual disc groups. Seems like a good QoL thing.

galaxybrain idea good job

Quite a clever solution. Sadly wouldn"t get a benefit from it before another round of retagging, since i don"t use disc subtitles yet, only realized they exist from this request. Would checking if anything else on the album has a nonzero disc number work as a condition too, or does that introduce other undesired effects?

Not sure. Zeroed values are removed during the initial round of tag extraction, so some heuristics would have to occur there. Do you use "total discs" values @illdeletethis? I could implement a check where zeroed discs are accepted only if the "total disc" tag is also present and non-zero.

[illdeletethis]

Great solution, yes, that"d work

[OxygenCobalt]

Okay, I'll do that and the subtitle check when adding this.

[OxygenCobalt]

Okay, I got this implemented.

Note: While I did add the total disc check to accept zeroed discs, I decided not to add the subtitle check, as it was much harder to test.

[KraXen72]

oh, the disc names wont make it into the app? i might also be misunderstanding this.

[OxygenCobalt]

No, disc names are making it into the app @KraXen72. They just won't factor in to the new checks for whether a disc number of 0 was intentional or not.
