Thanks for the comments guys!
M.Brane - I agree about the drum-track and the ride, but about the harmonies of the vocals - there's still too less structure in the song(well, there isn't any) , and maybe a bridge or two and a structure like Middleman suggested, will change the perception of the vocals..?
W.I.S.C. - I thing finally I understood.. no doubling by copying but by singing.. ok, well, is gonna take a lot of time, but at least it's vocal training; the guitars in the first part were ment to be not metalish in contrast to those in the second - however, seems that I have to retrack almost everything.. btw, the tape ran out cos this was just a "fist cut"
Joe - wellcome to the club - I'm just quitting (the flu-club hehe); like I said, the next version of this is gonna have a "song structure";
the "rushed lyrics" that you noticed, well, that was a failing attempt of rapping.. my rhythm section is still very weak, especially at the vocals, but I'll try my best next time
cheers!
