About this build v0.2.5

What changed

  • Collections over 100 songs now gain filters for artist, game/source, charter/author, genre, and year.
  • Expanded text search across titles, artists, albums, sources, charters, genres, years, and folders.
  • Added title, artist, source, charter, and original-order sorting plus one-tap filter reset.
  • Common game codes such as rb3 are presented as readable names such as Rock Band 3.
  • The audio-source panel now collapses after a song loads and reopens by tapping its compact summary.
  • Retained ZIP and folder sessions still let Choose another song reuse the original scan.

Known limitations

Source sessions last only while this page remains open. Switching ZIP songs reuses the saved index but still extracts and decodes the newly selected song. Browser codec support and decoded-stem memory remain the main compatibility limits.

Keyboard

Space plays or pauses. Home stops and returns to the beginning. Shortcuts are ignored while a control or text field has focus.

License notice

This build contains original HTML, CSS, and JavaScript with no bundled third-party runtime libraries, codecs, fonts, artwork, or songs. No project-wide open-source license has been selected yet. Users are responsible for having the right to use files they load.
