Recognize album artwork with "Album title.supported_extension" filename

[Gregory Opera]

At this time, Music currently supports the following filenames for local album artwork (i.e. album artwork which is stored locally in the same folder as the music for which it should be associated):
* cover
* album
* albumart
* .folder
* folder

These filenames must have one of the following extensions:
* jpeg
* jpg
* png

However most applications and programs also support (provided it matches the folder name and metadata album title exactly):
Album Title.supported_extension

I propose that "Album Title.supported_extension" be added to the list of recognized filenames for album artwork, to bring Music into line with most other music players...

Thank you for taking the time to report this bug and helping to make Ubuntu better.

The album art is done via the thumbnailer service, so I had added them to the bug report and set the music-app as invalid.

Others note this bug is a feature request, original discussion was bug 1607531.

Do you have any examples for music players that recognise <album_title>.<extension>? (I'm not aware of any at this point.)

The existing list of file names exists because they are widely used by various players, so we are just following established precedent here. We can look at supporting this, but I'd prefer to do this only if there are popular music players that already support this. If not, I don't think we'd be doing the world a favour by adding yet another file name convention to the already messy situation.

Whilst I can only speak for myself, I know that Fiio's music players support such a format for album artwork, and back when I used to use Microsoft Windows-based operating systems exclusively, a number of programs also supported album artwork in this format.

We also have Sony Blu-Ray Disk players and various-brand televisions that detect album artwork based on this filename format.
