Had a good one 154,000 - milked each board for points and got to the 4th wave. I am always scared of the bass guitar board. One badly timed jump...
In order of easiest to hardest (for me, anyway)
1. guitar (jetpack)
2. piano
3. microphone
4. drums
5. bass guitar
If you get all blue drums before reds, you get a 1,000 bonus. I haven't found a bonus on any other board. I like to hover and shoot left and right targets just below the finish line on the jetpack board until the 'fuel low' warning comes up. There are parts when you can sit and shoot those chains things with your drums for a while until they get faster, then it's time to cross the finish line.
On the concert stage, use your bouncer to keep out fans. The collision detection is generous, so you can only be partially blocking the door and still get 'em (stay towards the middle of the screen as much as possible).
