I am assuming you're talking about the song jackpot? You cash this in by lighting the canon (fire lanes), and then loading the canon (right ramp), and firing at the center drop.

Copied from my post in another thread..

There's some good info about this here:

My short explanation:

#of Jackpots to score Song Bonus) Album - Songs

1) TNT -TNT
3) LTBR - Let there be Rock / Hell Ain’t A Bad Place To Be / Whole Lotta Rosie
5) H2H - Highway To Hell
6) BIB - Hells Bells / Back In Black / You Shook Me All Night Long
7) For Those About to Rock We Salute You - For Those About to Rock
12) The Razors edge - Thunderstruck
15) Black Ice - Rock ‘N’ Roll Train / War Machine

The above is just for album mb, The order for tour is similar, though the shot number may vary. Basically, the songs are awarded in chronological order by album (or tour). A good strategy when you have a hefty Song Jackpot (SJ) built is to start something early in the chronology. In album MB, I usually start TNT, since you're also getting points for the drop targets. I basically limit it to a simple strategy. Before I start Album mb, if I like my SJ, I start TNT and then mb. If I don't, I start BIB and then mb. The latter lets you build your SJ before collecting it in the form of a Song Bonus...

Song Bonus is the SAME value as the SJ..except it does not reset. So, you could collect your SB at 20m, and shortly after, collect a SJ of 25m. After you collect the SB, your SJ will continue to build. But, after you collect your SJ, your SJ will reset. Because of that, It's a good idea to collect your SB first, in most cases.

Sorry, I've had some scotch, and I refuse to proofread.

2 ways...

As a SONG JACKPOT - as Robotoes noted (light fire lanes x3 and shoot right ramp to load cannon - then shoot at the bolt drop target). After collecting it will reset.

As a SONG BONUS - as my long-winded explanation explains - during MB you can hit the jackpot shot the number of times to correspond to the tour or album the song you're currently in corresponds to. Collecting in this way DOES NOT reset the jackpot total.

Well, now I'm not sure if you're talking about the song jackpot or the MB jackpot. The MB jackpot would be collected at the bell, I'm pretty sure..

He's talking about the Song Jackpot. Complete the fire lanes three times, load the cannon and shoot. That's it.
