Greets there fellas! This is an in-depth guide for those of us that just want to use all-talkie songs on vox for the most part of this ridiculous achievement.
The following set of songs are all-talkie songs which you can play on expert by pointing a fan at your microphone:
No Sleep 'til Brooklyn - On disc - $760 - 4:32
Grave Of Opportunity* - Free DLC - $665 - 4:15
On Broken Glass* - Free DLC - $625 - 3:50
Debaser* - DLC (160MSP) - $540 - 2:57
(All based on 100% with no SP usage.)
*Unfortunately, if you don't have these songs already, you can no longer get them, because most/all GH DLC has been pulled from the marketplace
because of licences expiring.They all work out roughly the same in $/min, once you factor in menu/loading times. So what I suggest you do is place all the songs you have in a setlist and play them all. The advantages being that you will only have to load the venue/setlist/etc once, at the end of a song the next song will be preloaded, making it a tad quicker if you move away from the 360.
If you don't have any of the DLC tracks, you'll have to repeat 'No Sleep' over and over again. It won't be
that much slower, but it'll take a bit more interaction to scroll and pick the song after each play.
If I'm missing a song or have made a mistake, please comment and I'll fix it up ASAP.
