Is there a good Android app that can download music from YouTube and other sites for offline listening?

Music Downloader & Mp3 Player is a dual-purpose application designed to both source and play audio content offline. For users looking to download tracks from YouTube, Facebook, or other video platforms to build a personal, offline music collection, this app addresses a specific need. It provides a built-in browser to navigate to video sites, and a prominent download button converts video audio into MP3 files stored locally on the device. The accompanying music player then organizes these files into a library, complete with standard playback controls, a sleep timer, and playlist creation. This is particularly useful for commuters, travelers, or anyone in areas with unreliable mobile data who want to ensure their music is accessible without a connection. However, it’s worth noting that the download functionality depends on the availability of the source websites, and some users report that download speeds can be inconsistent. The app also includes basic audio controls like a 10-band equalizer for sound customization. Reviews indicate it fills a niche for straightforward downloading, though the interface can feel cluttered with ads in the free version. For a simple, all-in-one solution to grab songs from online videos and manage them offline, this app provides a functional, if somewhat basic, toolkit.
