Play "Ride a White Swan"
Put on Super Easy
Place on short version (if applicable, the song is short enough to not have it last I looked)
The song is a very simple, slow beat, even more so than "We Will Rock You". You will see double notes, but don't pay that any attention! Just play whatever single drumpad is comfortable. Personally I just hit only the red drumpad the whole time while laying on the couch. Only thing to look out for is the last note which comes slight bit sooner.
--- I want to add that I didn't do any the drum fill sections for overpower/starpower and made sure not to have any extra notes.
