Guitar Hero 5

This guide should allow you to unlock "Score Biggest," "Score Bigger," and "The Streak" in one play.

I uploaded my own song, called "Score Big w star". The ones I was looking at didn't have Star Power in the songs, so I figured that was just wasting notes. Might as well get the 8x multiplier as well for extra points. I also used two sustained notes (green-red) instead of one.

I did this because I was having issues with Score Biggest, even using some of the songs on GHTunes, especially since a missed note or two meant that I wouldn't hit 3M even after 10 minutes. (Twice I got around 2.7M because I missed a single note.)

Same as other suggestions: one guitar, one drum. Set the drum up on auto kick. Play the guitar, and strum. Use Star Power as you see fit while the auto drum goes crazy.

It's 7:16 in length, so it isn't as long as some others, but you should probably get 3 million at about 5:50. Along the way, the drummer should get "The Streak" if they don't already have it (there are over 6500 drum kicks), so if you're doing this solo, log in on the drums and use the guitar as a 2nd account.

You can also make your own song, as others have suggested. That way you get the "Producer" achievement as well, like I did. :-) You don't have to use it, but I figured since I'd already made it, might as well post it. If it helps you, enjoy.

Edit: bbgmp reminded me that it would be good to put the auto kick cheat here for easy reference: YELLOW, GREEN, RED, BLUE, BLUE, BLUE, BLUE, RED. Thanks!

lightsup55 made a good point in the comments... To find the GHTunes song easier and quicker, search by File ID: 159148

GH™Studio -> GHTunes(SM) -> Search -> File ID -> 159148

My buddy made a song for guitar and put it on GH Tunes. It's called "3 MILL" that is just holding down all 5 fret buttons down and strumming a lot. Just search for it on Tunes and it's 10 minutes long. Keep your meter at 4x a lot and it comes fast.

Just play any song as a band (I did it with 3 people, inlcuding myself) on Guitars, two on Expert, and me on Hard.

We played the song bij Peter Frampton. We got around 6 or 7 million points, so 3 million is a peace of cake.

Just make sure you use Star Power all at the same time, and try to get a Star Power in the Band Section (glowing red notes). This gives you a nice X8 if you're with 3 people, and even x12 if you're with 4 people! Just make sure to have a x4 when you activate Star Power.

We had Star Power in a Band Section, and it got us a nice 800.000 points in only 15 / 20 seconds!

You can even play it all on Hard, then you still should easily net 3 million points, with Star Power (preferrely in the Band Sections).

You can easily do this if you create a song that is about 5 minutes long and only bass drum notes. I think you could easily do it with less than 5 minutes cus the one i made was 8 minutes and i got like 7 mil. anyway put the auto kick cheat on(cheats dont disable achievements in this game) then go do something else for the rest of the song.

Easiest way to do this, which can be done by yourself, is to download a song from ghtunes.

The song is called "Score Biggest", so just type that in the search and it will come up. I didn't create the song, I just found it.

Download it and plug in a guitar for you and a drumset for nobody. Put both on expert because the song is super easy. Turn on auto kick for drums, because all the drum notes will be kicks (and therefore your empty drumset will get 100%). The guitar part is just a bunch of long sustained green notes.

It's a boring 10 minute song, but you will definitely get over 3 million when you and your empty drumset both get 100%.

Achievement unlocked. Minimal effort. And you will also get the "Score Bigger" (for scoring 1mill as a solo or band) achievement if you don't have it already.

I did this with two guys, I was on expert bass, they were on hard and expert drums. We did "Do You Feel Like We Do (Live)" by Peter Frampton.

I hit about 98% and they hit 94-99% and we got over 4million points.

I got this by playing Wild Cherry's Play That Funky Music on Xbox Live. I was on Expert Guitar, and there was at least 1 other expert player (drums probably). It was not that hard, I didn't get 100% and we still got it... easily. In the end we scored well over 3 million.

Make a song using the guitar to make the drum track. Put a LOT of open strums for the bass pedal.
Put auto kick on.
Then just make enough strums to get 4x on Guitar, and make the last note for 4x a start power phrase. Use whammy and star power and you won't run out.
Simple.
Works for 1001 note streak achievement as well.
