The audio playback unit plays the audio files. The display unit shows the lyrics and is a touch-enabled display. The method includes directing the audio playback unit to play an audio file back, implementing the timer, directing the display unit to show the lyric content, determining the lyric content displayed corresponding to the contact position and determining a time tag before the determined lyric content according to the recorded time; and updating the time tag with the determined time tag before the determined lyric content with the determined time tag when the lyric content is not displayed synchronously with the current audio file.
