MrTux Music Collection is a complete WordPress plugin that lets administrators manage a collection of audio tracks through a dedicated control panel and expose them on the public site via a shortcode with a modern, responsive audio player. It is free and fully functional on its own — no purchase required.

Features:

Custom Post Type music_track with title, description, artist, album, cover image, and audio file upload via the native WordPress media uploader.
Custom admin list table with bulk actions (publish, draft, delete), single row actions, search and pagination.
Shortcode [music_tracks] with parameters: limit, orderby, order, artist, show_cover, show_share, layout.
Modern HTML5 audio player powered by Plyr with one-at-a-time playback (playing a new track automatically pauses the others).
Automatic duration detection: as soon as the audio file is selected in the editor, the browser computes the duration and persists it via AJAX.
Share buttons for WhatsApp and Instagram on every track (Web Share API + configurable Instagram profile fallback).
Track categories with hierarchy support and grouped display.
Clean, conditional asset loading: CSS/JS are enqueued only on pages where the shortcode is present.
Fully internationalized, .pot file included.
WPCS-compliant code, with nonces, capability checks and proper sanitization/escaping everywhere.

The Pro edition

For creators who need more, MrTux Music Collection Pro adds:

Continuous playlist player: a single global player with a visible queue that keeps playing the next track automatically.
Canvas waveform progress bar for every track, with click-to-seek.
One-click download buttons for every track.
Dedicated Pro settings page (autoplay, download defaults).

MrTux Music Collection Pro is a separate add-on, installed alongside this free plugin, available at https://wpforge.site/music-tracks-pro. This free version is complete on its own and does not require any purchase.

How to upgrade

Visit https://wpforge.site/music-tracks-pro and download the Pro add-on.
Upload it via Plugins > Add New > Upload Plugin.
Keep both plugins active: the Pro features appear automatically (e.g. use [music_tracks layout="playlist"]).
