i was an english major, and my single natural talent is for spotting typos and errors and stuff, so i probably should be a professional editor. i guess being a high-school english teacher will be fine, though; my kids' papers are going to be heavily red-marked.
i can't devote the time to actually scour it, but on a glance i see that you have "Leaving you Body Map" instead of "Leaving Your Body Map", and also:
"but on this one they seem to take center stage in some parts of the song, and add a nice musique concrète atmosphere to the song."
no comma necessary there. and in the following line, "seems" instead of "seem".
"This one uses sound manipulation in a very similar way Fly Pan Am did on the latest, electronics just weave around the analogue sounds in perfect harmony to add rather than distract"
semicolon instead of comma, and you could add a comma after "add" if you wish, but it's not necessary (I don't think).
" is one of their trademark, this one part would have fitted "
trademarkS. also, change the comma to a period, and capitalize the T in "this". "fit" instead of "fitted".
there's more but i lost patience! sorry!
