Super slow add function for queuing songs

[nukem85]

I stood out with this for more than 2 years now.

When I add a song. That ridiculous slow gray bar has go all the way back. Before I can add a new song. Not even does it have to go back. Directly after queuing a song I will wait some time for it to even start going back.

And If I try to add another song within this time. The gray bar has not gone all the way back. My second queuing gets interrupted. And I have to start over once again.

This maybe does not sound as a big of a problem. If you are slow there is no problem. But when I am making playlists of 50 songs. A couple times every week. I am spending more time waiting for your code. Than adding songs.

Please take away all the waiting events. There is absolutely NO NEED for them.
