Addition of "bottom bar"

[AdnanHodzic]

I love Music Plus for Google Music extension, it basically gives me everything I need.

However, there's a problem that is more annoying rather then being an actual problem; and is solely of visual nature. I have no idea what triggers it, but during some time additional bar on the bottom appears, or the bottom css background part gets extended (?). Either way I've made a screenshot to "illustrate" what I'm trying to say: http://goo.gl/kbgrP

First I was certain track change notification caused it, then I tried to turn of "Show notifications when tracks change" option which didn't help. Basically there's no workaround, however what I did noticed that sometimes works is if you have list of download/ed file/s at the bottom and when you clear that list that additional bottom bar disappears with it.
