Great channel presentation and using your logo here, it's great for your branding and making your name known. I agree with Gingee about the black and white video, if its a problem you may want to get that fixed so they're in colour and look better to your viewers. It also isnt so good going from colour to black and white.
I have used incompetech a few times before, it seems there are hardly any royalty free and free music out there other than there and a few loop sites but theyre not exactly full tracks.
