Easy% is roughly half an hour quicker than hard/expert% since you only have to play 4/5 songs in each tier (apart from the last one), and there's no tier 6. The run is identical to medium% for the most part, but I'll include everything.

Be sure to play songs from top to bottom to reduce the amount of menuing that you have to do. Also turn off saving!

Tier 1 - Skip Smoke On the Water (song 4) Tier 2 - Skip You've Got Another Thing Comin' (song 3) Tier 3 - Skip Hey You (song 2) Tier 4 - Skip Ziggy Stardust (song 1) Tier 5 - Play everything.
