After last night's events, I'm thinking this post will erase most of the misunderstandings and such among the fans.
Before we move on, I'm going to tag some of the tracks that requires a little bit effort to find as rare material. This is because of the fact that I have no idea which one is spread/leaked, they might be online but just not in plain sight etc. Maybe you can find them on some website, maybe someone will be kind enough to share them with you or maybe they are already on Youtube. I don't know but in the end, they will be our rare stuff.
Album Samplers
Album samplers are promo CD's that were mostly found on eBay. After me buying the last pink sampler, both of them are all sold out and not available anymore. Fans bought what was available at the time and traded for the rest.
1. Youth [3:58]: The oldest version of Youth. (Can be easily found)
2. Echo [3:44]: Radio edit. (Can be easily found)
3. Let Go for Tonight [3:43]: The oldest version of LGFT.
(Rare)
4. Glorious [4:49]: The demo version of Glorious which is longer & leaked last month. (Can be easily found)
5. Beauty Queen [3:53]: First demo.
(Rare)
(I bought the last copy of this sampler.
)
1. Youth [3:45]: An alternative version of Youth that is very similar to the radio edit in terms of length.
(Rare)
2. Heaven [3:11]: An alternative version of Holding onto Heaven.
(Rare)
3. Night Owls [3:29]: Possible album version of NOEB. (Leaked recently)
4. Glorious [4:22]: Possible album version of Glorious. (Leaked recently)
5. Count the Saints [3:35]: Possible album version of CTS. (Leaked recently)
6. Night Glo [4:24]: Possible album version of Night Glo. (Leaked recently)
So far so good? Great. Let's look on tracks one by one.
Glorious
Talking to Ghosts: A demo (leaked recently - 10 seconds longer than the final) and a live version (on Youtube) is available.
Youth: Two different versions from the samplers, the single/album version, orchestral and instrumental. (+ Radio and video edits which are only different in length)
Holding onto Heaven: Single version and Heaven from the sampler.
White Coats: The version on the Warrior EP and possible album version which is featured on the video (similar to Echo), + instrumental.
Shaking Heads: Officially released, will be a little shorter on the album.
Let Go for Tonight: One version on Warrior EP, demo 1 from the first sampler, demo 2 which leaked last year, single/album version + instrumental.
Echo: Radio edit (rare), instrumental, acoustic, bunch of remixes and a possible album version (longer intro/outro - nothing major) is available.
Clarity: Album version which was featured on Zedd's, radio edit and the live version on Glorious, released as free MP3 download on Amazon.
Beauty Queen: Demo from the first sampler, a second demo which didn't leak and is rare, also a rare radio edit + the single/album version.

I hope things are more clear now for you. If I made a mistake (for example writing wrong quality or giving wrong information) please warn me so that I can edit it out. Don't hesitate to ask if you have any questions. That's all for now.
We don't know for sure that it's the album version, but it's the final we have in our hands, it's just a little longer than the radio edit but no major differences whatsoever. 
The second Beauty Queen demo is more rare than that.
