" A little side note on HOPOcidal Maniac (and all related goals): Tapping during the solos DOES COUNT TOWARDS THE GOAL. If you tap a note and then tap a HOPO after it without breaking streak, it will count as a HOPO instead of a tap. Those of you that exported Rock Band 1, get used to grinding Green Grass And High Tides if you want the goal fast. Alternatively, wait for the Harmonix Free DLC (the tracks from RB2 by Harmonix bands) to hit and grind Visions if you can consistently FC it. "
Interesting. Why would you be grinding GGaHT though, when there better songs on the RB3 disc you could be grinding? (Free Bird comes to mind)
I'd rather just get it by playing normally though. I'm not in a hurry to unlock achievements.
