Well, each one has its own appeal, which is what I find so incredible about LPU9; they're finally doing something right.
A.06 long version would just be plain epic, since the short version of the song is already so.
The original Faint demo was said to be almost twice as slow, meaning that this is going to be quite interesting (on a side note, when slowed down, it sounds just like from the inside).
The By Myself demo is an alternate demo of the demos we already have, so we can expect something interesting from it.
Fear is going to rock, because most likely it's going to be Mike's vocals with alternate lyrics on there.
Figure .09's demo is most likely going to be the one with Chester singing during the verses, as opposed to Mike rapping. The large change is probably why they picked it in the first place.
Stick N move is going to be epic because it's going to be a CD quality version of a demo, most likely with Chester doing the vocals, and Mike sounding more like he sounds in the HT era.
Across the line should be self explanatory; though when I first learned that it was actually Japan I got thrown off (not in a bad way, I just entirely did not see it coming).
Drawing is supposed to be the BTH demo instrumental that was what, six minutes long? Something around that. Always good to hear an extended instrumental of a song that everyone likes.
And lastly, Drum Song, which will be incredibly awesome because Mike will be on the vocals (we can hear a clip of it on one of the LPUTVs when those few LPUers won that referral contest).
This is a dream to any hardcore LP fan. Let's be happy that the LPU is finally doing something right (as opposed to LPU7).
Oh, and I guarantee that once the CD leaks, SOME people are going to be like "OH WOW THIS CD SUCKS WHAT DID LP DO THE DEMOS SUCK AND SO DOES ACROSS THE LINE LOLOLOLOLOL"
The people who say that can finally be identified as the LP fans who are never happy with anything the band does.
