Yeah... that someone is us... and we are ADDICTED.
Check the time stamp and you'll understand. I'm on the 8th level of hard and I think I'll be stuck for a bit. This one is definitely harder than the others. There are a lot more 2 and 3 note combos on hard and there are a ton of really fast songs on the new one. Every game so far I've gotten (permanently) stuck on one or two songs on expert... which is incredibly frustrating.
Hang in there Danny... it will click all of a sudden and you'll start hitting stuff you thought you never would.
Funny as it sounds, playing has definitely made my fingers a lot more nimble and has taught me to keep a much tighter beat, which are really the only things that have actually helped my real guitar playing. If only I could pull off some of these solos...
