Media Control not functioning at all? what am i doing wrong?

I'm sorry. On this screenshot Media Player shows "JDast_error". I thought this is the error message. But on your last screenshot I see the "JDast_error" is the mp3 title you have in the AIMP3. So Media Player is working with AIMP correctly.

Add other music into AIMP and you'll see the titles and can control AIMP.
