Amarok 2.8 High Memory Usage in Kubuntu 16.04?

Question

On a brand new install of Kubuntu 16.04 I have noticed that Amarok is the biggest memory hog right from the start with 450Mb.

The same Amarok version on Kubuntu 14.04 uses only 75Mb.

Any hints or suggestions are greatly appreciated.

Edit 1:

I looked at the detailed memory usage of Amarok in Kubuntu 16.04 and 14.04 and pasted a small portion of each below. Each process invoked seems to be 2~3 times larger in 16.04 than in 14.04.

In 16.04 I have:

Memory usage in Amarok can be decreased by changing the phonon backend from gstreamer to phonon-backend-vlc. Run the following:

sudo apt-get install amarok phonon-backend-vlc

Then open Amarok and follow this trail:

Settings > Configure Amarok > Playback > Configure Phonon > Backend

And when you are there select vlc, as demonstrated in the screenshot below:

As you can see you now have the option of switching from one backend to the other; useful if you wish to generate some hard statistics of memory usage with the different backends....
