— Description of the Useful Music Player —
This is a built-in music player app for Android, following the specifications of external (microSD) or internal memory. Note that it may take a few minutes for Music ID search during initial startup.
◇Starting from Ver1.5.0, it supports gapless playback, making it more comfortable to listen to non-stop song collections.◇
A feature of this app is the ability to disable (skip) songs by checking a checkbox for each song. This allows you to skip unnecessary songs such as instrumentals in a single.
You can easily create playlists by long-pressing on the list view. There is also a link to Google search for lyrics.
After narrowing down songs with a search keyword, you can easily create a playlist of all songs in the settings under “Add all music in all lists to playlist”. The app also has an off-timer function, allowing you to set a countdown time in 5-minute increments from the timer button for forced termination of the app.
Simply tap to play from the list, or press the play button to play from the beginning of the list. The repeat button allows you to select no repeat, repeat one song, repeat all songs, or execute shuffle after repeating all songs (and then play from the first song). You can shuffle songs within the list and rearrange the song order after shuffling.

You can use =, &, and | to separate search terms. Note that parentheses are not supported.
“&” represents “and”, “|” represents “or”, and “=” is used for element specification.
By typing “Takehara｜Yakozen”, you can easily extract a mix list of all songs by Takehara and Yakozen.
You can specify “TITLE”, “ARTIST”, and “ALBUM” as the element before “=”.
◇Starting from Ver1.5.0, you can exclude elements using “^” at the beginning of the search term.
For example, “ARTIST=Nakajima&^Jidai” means exclude songs containing “Jidai” by the artist Nakajima.◇
