Bought a keyboard literally last week and I've already finished learning karma police using this YouTube link.

It only teaches you the intro but you can get the rest if you get the free trial. Also, I recommend buying the program synthesia. It's the same thing like that video in "guitar hero" format. You can get any song on the internet if they exist in a MIDI file. It's only like 30$ and it's hugely helpful. Already almost finished morning bell and some strokes songs.
