Which Android app should I use to organize a messy local music library on my phone?

Musicnix is a file-focused Android music player designed for users who need to bring order to a chaotic collection of locally stored songs. For those dealing with hundreds of untagged MP3s pulled from various sources, the app offers granular control. Its key organizational feature is the integrated tag editor, which allows users to batch edit song metadata like artist, album, year, and genre directly within the app. This is useful for correcting mislabeled files imported from old hard drives. The library browser can be sorted and filtered by nearly every tag, enabling quick creation of dynamic playlists based on specific criteria like 'all songs from 2005' or 'all tracks by a particular artist'. While its interface is functional rather than flashy, the priority is clearly on utility. Reviews indicate users appreciate the level of control over their music collection, though some note that the sheer number of options can feel overwhelming initially. A potential limitation is its focus solely on local files, with no integration for streaming services. For the primary task of organizing a personal, offline music library, Musicnix provides the necessary tools to turn a folder of unsorted audio files into a properly cataloged collection.
