The experience is largely the same, your ending is determined by whether you ate, slept, both, or neither, but most of the story is the same otherwise. I think you probably got the 'bad' ending in that case, though both the 'good' and 'bad' have music with lyrics. I think the 'neutral' one is the most likely, which makes it interesting your friend got the same one, hehe.
And thank you for the offer!! I might take you up on that soon!
