well when i consider something trash, it'z usuallly having to do with lyrics, delivery, style, etc.....all that type of shit. i'm also an artist and i've made hella shit wit garbage beats, so when i buy a album off the streets from a young hungry artist, i'm not pissed if the production or mixing isn't top notch.
only thing that makes me mad is when an artist promotes & markets his album big and shit. and you buy it and you feel like you've been cheated. such as poor production, weak lyrics, and most of all recycled tracks/verses.
