i just had to donate a few hundred lp's to thin my collection 1 shelf. so that hurts. it was mostly doubles and garbage but i had to let some decent stuff go. made a trade and bought a few more better ones. as far as modern electronic music, anyone using it to test anything in audio has already lost the battle. no way you can determine what's pumped and crushed in the mix verses your system. they probably have wireless speakers too. nothing audiophile about any of that. wires, uncompressed (data) audio files, professional compression on the mix, and real instruments and voices are needed for the full effect. sure it can have synth and funk or rock in it but it needs to have air and breath and emotion to test a system. recording and then playing music = conveying emotion. you have to have it in the first place to convey it and measure it.
