Green Day Rock Band

Here's a list of the 20 shortest songs in the game. Times in parentheses are based on run times listed on iTunes.

1. Song of the Century (0:58)
2. Coming Clean (1:35)
3. Emenius Sleepus (1:44)
4. In The End (1:46)
5. Burnout (2:08)
6. She (2:14)
7. Geek Stink Breath (2:16)
8. Pulling Teeth (2:31)
9. Good Riddance (Time of Your Life) (2:35)
10. Sassafras Roots (2:38)
11. Having a Blast (2:45)
12. Minority (2:49)
13. Nice Guys Finish Last (2:49)
14. F.O.D. (2:50)
15. Hitchin' a Ride (2:52)
16. Chump (2:54)
17. American Idiot (2:54)
18. Murder City (2:54)
19. When I Come Around (2:58)
20. Basket Case (3:03)

If you're playing Guitar/Bass/Drums and can't play Song of the Century (or Good Riddance on Drums), next on the list are Horseshoes and Handgrenades (3:14) and Peacemaker (3:24). If you have the DLC, Christian's Inferno and Know Your Enemy are both shorter than Horseshoes and Handgrenades and Peacemaker (3:07 and 3:10 respectively).

So there's the quickest route. Keep in mind that you still have to be able to pass the songs, but you can do this on any difficulty, so that shouldn't be too much of a problem.

UPDATE: It has been confirmed that playing a setlist on Easy and letting it sit around does NOT work. The game still treats this as failing, even though no-fail is enabled.

UPDATE 2: According to the comments, playing on Easy automatically disables the achievement, even if you don't get into the red, so you may have to play the setlist on Medium or higher.

UPDATE 3: If you're playing this multiplayer and one person fails out, even if you save them, it still negates the achievement.

I HIGHLY recommend doing this on bass and pick 20 songs you have not played on bass. That way you can work on this achievement and the one that requires 3 stars on all songs on bass.

To start a setlist go to quickplay and hold down the green fret and it will open up a set. Don't play on easy or you won't get the achievement since it automatically turns no-fail on. You can pause, this is not a bladder of steel type of thing.

Be careful though and don't pick a set you can't play. This game has some really fun and tough songs on bass, just don't bite off more than you can chew!

This is one of those great achvs that you can get multiple achvs while grinding out the 20 songs. As Spectrix solution points out, if you use Bass, you can also work your way towards


There are also other options to consider such as the 1million point career achvs. These will unlock naturally as you are playing through your 20 song setlist. I got mine on Drums




If you choose to go the vocal career, you should also get


***Confirmed-You can also get this achv***
I haven't confirmed this yet but it may also be possible to get

As I am not sure if you specifically need a 6 song setlist of a song from each album or whether it will work in longer setlists. I am going to confirm "The World Around" achv and update the results. Just make sure you have at least 1 song from each of the 6 albums.
***Confirmed-You can also get this achv***

*Just remember as it has already been pointed out, you have to play on Medium or higher difficulty to pop the achv*

Hope this helps.
