What's your favorite song purely based on how fun the chart is, not how much you like the song.

My favorite has to be Lay Down in Guitar Hero 3. I don't even listen to Priestess, but it's just so fun to play. Everything feels like it flows together so well. And my fingers are just dancing up and down the neck over and over again. It also just perfectly fits my skill level as a casual expert player. I'm always challenged by it but I can always get a 5 star if I lock in. That's why it's my go-to warm-up song.
