Hahah, cool thread. I can totally relate.
I don't let anyone listen to 90 percent of my music, I barely uploaded anything here even.
..but this one time, my friends asked me to make a theme song for someone. They specifically requested lots of bass and siren sounds over a recorded sample. Well I did just that, made the bassiest loudest and craziest song for them. One day they were throwing a party, there were ALOT of people there, and they decided to turn off the music and announce that they were going to play my song... I was like UGH, felt like covering my face and walking out, because they played it on a 20 dollar stereo and it sounded like.. well, playing the worst song ever full blast on a 20 dollar stereo. So while these gargly crunchy sounds are coming out of the speakers, along with sirens and someone yelling "jello", everyone just stopped and looked around at each other in evident bewilderment, wondering what the hell was that.
Since then, I stopped giving music to people, for the most part. I still feel like I need to redeem myself, but meh..
