### The Unpopular Music Player

#### Unpopular Player or Unpopular Music?

This ambiguity only works in English. In other languages it would be clear if either the music or the player is unpopular.
"Unpopular" itself is a pun I got from here. As "pop music" means "popular music", any other music obviously must be unpopular.

#### Why the (n + 1)-st Music Player?

The Unpopular Music Player (UMP) is not designed for pop music only, but also deals with work, composer etc.. Further is does not truncate long work and movement names. The goal is to present a work in the same way it would be presented on a CD box or in a concert programme.

By the way, the word "song" is not used in its user interface.

#### Tagging of Audio Files

Since version 1.42 the Classical Music Tagger can be called directly in the program. To do this, open an album and long-touch a single track until the query dialog appears. Alternatively, long-touch the header (image or text) to send all tracks of the album at once to the Tagger. If the Tagger is not installed, you will be directed to the Play Store. Note that you can also start the Tagger "standalone" and navigate through the directory tree.

Please note that changes to the files will not be visible immediately, but only after the Android system has updated its database and the UMP has been restarted if necessary.

Of course the application can only show what is stored inside the music files, in the so called "tags" (meta information). If these are wrong or incomplete, one could use handy applications like Kid3, Qoobar, iTunes or similar to repair or add information especially for classical music. Additionally to the usual meta information, like "album", "track number", "CD number", "title", the Unpopular Music Player mainly relies on "composer" and "group" (used for work), but also shows "year" resp. "date" and "conductor", if existing.

When editing meta information one can either use standard tags or iTunes tags.

Standard tags for mp4 files are:
- ©nam for title or movement name, including movement number, e.g. „I. Presto“
- ©grp for work, e.g. „Sinfonie Nr. 8 h-moll, op. 42“

Standard tags for mp3 files are:
- TIT2 for title or movement name, including movement number
- TIT1 for work

The problematic behaviour of iTunes, especially concerning mp3 files, is described in the following chapters.

#### Metadata Behaviour of iTunes

Use Work and Movement OFF:
- MP3: "Grouping" -> GRP1 (Nonsense, must be TIT1)
- MP3: "Title" -> TIT2
- MP4: "Grouping" -> ©grp
- MP4: "Title" -> ©nam
Use Work and Movement ON:
- MP3: "Work" -> TIT1 (Nonsense, must be new one)
- MP3: "Movement Name" -> MVNM
- MP3: "Number of Movements"/"of" -> MVIN
- MP4: "Work" -> ©wrk
- MP4: "Movement Name" -> ©mvn
- MP4: "Movement Number" -> ©mvi
- MP4: "Number of Movements" -> ©mvc
- MP4: shwm := 1
Use Work and Movement ON->OFF:
- MP3: no file change (Nonsense, change flag or remove tags)
- MP4: remove shwm

#### Metadata Behaviour of this Program

If movement name exist (©mvn or MVNM):
- Get movement number (©mvi bzw. MVIN), precede it to movement and use as title
- Get work (©wrk)
- If work does not exist or file is not .mp4, get "©grp" or TIT1
- If these also do not exist, get GRP1
Otherwise (i.e. no movement name):
- Get title as usual (©nam or TIT2)
- Get "©grp" or TIT1
- If these do not exist, get GRP1

#### Folders and Album Titles

A sensible organisation of music on the device is to use one folder for each album, and additionally to the music files (mp3, mp4 or similar) this folder should contain a picture called "folder.jpg" in order to help the Android system with file and album management. By the way: files named like "frontpage.jpg" would be shown the photo gallery, which usually is unintended.

#### Media Database

By default the Unpopular Music Player uses the media file management provided by the Android system. In case the information shown is wrong or inconsistent, there are some advices to rebuild the internal media database. What could work is to clear all data of the internal "Media Storage" (recommended for 4.4) or of the standard music play application (recommended for 5.x), to reboot and then (for 5.x) start the standard music player again.

If the Classical Music Scanner is installed, one can alternatively use that one to build the database. Check the box in the settings/playback modes at "Use own database." An additional advantage of this method is that the album list is already complete when loaded, i.e. with album length, album interpreter and composer and so on. Also there is no need for the program to access music files when an album is opened, because all metadata are already complete and correct.

In case of problems with the database file the Android database will be automatically used again.

#### Final Words

Writing this application took lots of time, and putting it to the Play Store took both time and money. However, I decided to provide the application free and without advertisements for people liking classical music. So please rate this "opus 1" benevolently and in doubt first send me a message instead of providing a bad rating.
Thanks in advance!
