L1 (Loneliness): 0:00 - 8:20
L2 (Liberation A & B): 8:22 - 13:43
To have it cleared up, there were some (many) confusions when it came to the naming of the different L parts ICE composed, whether they were made for Cytus/Deemo or just standalone compositions.
The first L (L1) is not called Lost. It's called Loneliness, according to Cytus' Chapter L naming. Lost is L8, and has nothing to do with the first 2 parts of Chapter L, L1 and L2 (It's hella different from the ones you've heard already).
The album version of L included the extended version of the first L (Loneliness), then both L2s (L2A and L2B, which are named Liberation), and then after Liberation played another part which was unclear whether it was Leverage (L3) or not.
Thing is, it wasn't L3 (since it also sounds hella different from the first two parts).
It's just the rest of L1 (Loneliness) that was not included on Cytus due to lack of space to include it as a secret song or whatever.
If you look up L1 (Loneliness) from Cytus and listen to it whole, you'll notice that the second half of it sounds exactly as the last part of the Album Version of L.
So yeah, I thought I might as well rearrange the parts correctly so that they follow up accordingly, based off the order of the parts in Chapter L on Cytus.
After this, comes L3, and then L4 and so on until L10.
...and then ICE released L0 the conclusion over at his "Shota Paradise" album. Said song should probably go either before L1 (following numbering order) or after L10 (since it's "the conclusion"), but I think it's better to leave it at that.
