iSoong - Like moving badges

When storing a large amount of music in a music player app and listening to a bloated playlist, it inevitably becomes difficult to manage. So I wanted to create an app that would allow me to manage songs by album, for example, and make it easy to remove groups of songs from a playlist or add entire albums to a playlist. Additionally, there are currently very few music player apps that can display the audio spectrum, which was another motivation for us to implement this feature.
