The so-called PSP-like music player is simply based on the waveform that comes with the PSP, used as a background. I偶然 found a very helpful waveform effect online (http://www.anttikupila.com/) and added it to an older player (as3-lrc-mp3-wave). By tapping the screen, you can switch waveforms; lyrics are displayed on the top, and the song info is shown at the bottom. I removed the volume control and playback time selection because I felt that adding these elements would make the interface too cluttered.
