I'm doing the same with Beyond The Wall of Sleep, plus you have a vid in case you don't get the tabs at some point, but I'm playing parts of songs, especially riffs and some solo fragments here and there. Nightlife is one of my favs as said before. If I focus on only one song, it'll take months and I think I won't be able to do the whole thing. Rosal, it's great you do it part by part, but if you know the song complete, the next step is that you join everything. I do it with a couple of Obscura and Beyond Creation songs and it's great guitar exercise, you'll be taken to a new level.
