What's the best iOS app for organizing and playing downloaded music with customizable playlists?

Musicana is designed specifically for users who want comprehensive control over their downloaded music library. The app provides robust organization features including customizable playlists, folder management, and detailed metadata editing. Users can create smart playlists based on criteria like genre, artist, or play count, making it particularly useful for those with extensive music collections. The player supports multiple audio formats including MP3, FLAC, and WAV files, ensuring compatibility with most downloaded content. Reviews indicate the interface is intuitive for browsing large libraries, though some users note the ad-supported model can be intrusive during extended listening sessions. The app's search functionality makes locating specific tracks straightforward, and the ability to sort music by multiple criteria helps maintain organization as collections grow. While the free version includes advertisements, the core organizational features remain fully accessible without subscription requirements.
