Excessive CPU load playing song.

[ManMachine]

I noticed since the last two .deb updates that the CPU fan was running quite much and wondered what happened.

It turns out that playing a song draws ~50% cpu for the most active process + a few more at 5-10%.  For just playing sound this is massive!

The UI is also very sluggish, and when operated the main process goes over 100% (in top).

What gives?   Should I feed it some options to get rid of this?
