in defense of electronic sequencing and audio production:
1) i think a lot of people go for synthetic sounds not because it's "the easy way out," but because it sounds better in certain occasions. honestly. a death metal kick would not sound very glorious in an epic trance song [unless you're saying the whole concept of electronic music is bad... which i'd really disagree with.] synthesizers really do give a different vibe to a song than a traditional acoustic guitar would, and you can' t really escape that.
2) but even apart from that, look at it this way: a composer doesn't have to play the sounds perfectly, he would be writing down the notes as notation as the production of the song. so visualize electronic sequencing as that composition phase. when people actually perform stuff live, most of the good people indeed do do audio editing live [or you'd get a very boring batch of concerts].
3) and even ignoring that, a lot of sequencing can be really really hard, on the other hand, if you're actually tweaking instruments like crazy. while commericalized, usual stuff generally doesn't go very deep into that, vocal splicing and twisting samples around like crazy [try akufen for some lighter stuff.. kid606 for some really heavy stuff... and maybe some idm or some good drum and bass artists for complicated arrangements] could be tough as balls. audio processing doesn't really happen as much when ur just strumming an acoustic guitar, so that throws in a whole dimension of difficulty even though laying down notes isn't hard.
4) i see where you're coming though--i play piano--and once you get proficient, basic audio production does get easier. but when you're faced with the expectation of something completely different every time [complete overhauls of every instrument? you don't really do that much in traditional songs], the expecatations are raised as well.
though, those expectations happen to be really low on newgrounds because it is an environment conducive to total n00b composers, hence the following overinflated ratings compared to the record industries and professional scene.
