The application only works in the foreground. For its functions to operate correctly, it must remain open or in windowed/shared screen mode, as permitted by the device and always manually activated by the user. It does not run background processes, nor does it continue to detect audio if the screen is minimized or locked.
The system detects only genuine songs played from the device's storage or from sources compatible with metadata reading. It does not identify voice recordings, audio notes, ambient sounds, or audio from other applications. Its engine is designed to recognize only valid music files and differentiate them from any other type of audio.
Once a song is playing and the application is active, the system immediately displays the images the user has selected from their gallery. These images are only displayed while the song is playing; if the track stops, changes, or pauses, the image display also stops to maintain precise synchronization.
