there are some people who are pretty narrow minded. some of my non-musical friends don't like sampled beats so when they hear my composed beats or anything that sounds more radio friendly than what i choose to make, they like to tell me i'm "getting better". i'm not "getting better", i can make radio sh*t, i just choose to make what i like instead.
that being said, you should choose whos criticism is relevant and whos isn't. but the main point is don't take it personal.
