Command Line-based music player in Linux

According to my colleagues, I am an excellent command controller.
I wrote a music player under the command line to meet my linux Command requirements during the idle time of the latest project.

Player exploitation technology:
Python + GST (html ">Http://gstreamer.freedesktop.org/modules/gst-python.html) + Console Parsing

Player self-sustaining operations:
1. Play
2. Next
3. Previous
4. Pause
5. view the playlist Information
6. view the current playback Information
7. Stop (Exit)

Take a look:


By analyzing the memory information dumped by meliae dump, the memory usage is less than MB, which is relatively small.
