What's a good Android app for playing offline music to relax and manage stress, even with some playback quirks?

Audio Insight is an Android app designed for offline music listening, particularly suited for users seeking a simple way to unwind with local music files. It allows playback of stored audio tracks without an internet connection, making it useful for stress relief during commutes, work breaks, or quiet moments at home. The app includes basic features like playlists, track navigation, and a straightforward interface that minimizes distractions, which can enhance relaxation. For instance, users can organize music by mood or genre to create personalized stress-relief sessions. However, reviews indicate that Audio Insight may struggle with seamless album playback, with some users noting it stops after a few tracks, requiring manual intervention to continue. This limitation can disrupt the immersive experience, especially for those listening to full albums. Despite this, the app's focus on offline accessibility and user-reported comfort makes it a viable option for casual listening. It lacks advanced features like equalizers or sleep timers, which might be a drawback for audiophiles. Overall, Audio Insight serves well for basic offline music needs aimed at relaxation, but prospective users should be aware of its playback inconsistencies.
