I would actually move the Almost Famous moment closer to the top. That to me is one of the best music moments in film. And it's a lot more interactive than a lot of the other moments.
Yeah, I guess the important point of this reference is that the characters are actually participating in the song. Most of the others (that I've seen) is just the perfectly timed soundtrack choice that makes it important. I guess the Reservoir Dogs
one is part of the plot too, a little bit, but Tiny Dancer is clearly what's bringing the characters together.
Plus, that movie changed the fondness for Tiny Dancer forever after, you know?
