I think everyone in this thread has either been responding to the title of thread or responding without actually listening to the songs in question
all three of which are absolutely horrible examples of the point being brought up
I hear little to no 8-bit influence. what you appear to be pissed about is simple analog synth sounds. but even then, most of the sounds are just layered saws or other standard trance/electronic sounds that have bled into pop and hiphop in the last 10 years... not 8bit
the reason people think 8bit music is "uncool"-- and for the record, I share your outrage about knee-jerk dismissal of chiptunes-- is that 8bit sounds like this: http://soundcloud.com/heathmorris/heath-morris-secret-menu-memories-gameboy-camera-remix
and it reminds people of old video games. games they don't play anymore and have probably somewhat blocked the memory of due to polarizing it against something "cooler" like sports or being a really broken person
bottom line is I agree with you. it sucks that TOTALLY CLICHE synth textures and HYPER-SIMPLE melodies with TOTALLY CLICHE drum samples and COMPLETELY BARE soundscapes top the charts, while dedicated songwriters/producers have to slowly build an audience. thanks to the internet, I prefer the latter
anyway, I'm just gonna leave completely off-topic item here: http://www.youtube.com/watch?v=szlk9eMWkpU
