So couldn't they remove the vocals from the rest of the album/s and put it to download on their site...?
They had to redo the actual instrumental. You just cannot take the vocals out of a studio recording. only 10% of the time it will work, and if it does it will leave you with a blurry soundfile. Also, LP embeds vocals in the beats, so any vocal remover you try on it is useless.
I'm sure they could with the expensive equipment they have, but why would they want to? There would be no point.
actually the instrumental were on the forgotten (reanimation) single. there were 4 songs on the single, the reanimation versoin of fogotten and in the end, plus the demos, and the cover of the single looks just like one of the parts of the reanimation cover. the single is very rare and it was given out to contest winners in the lpu.
