I listen to classic rock, blues, soul, R&B, jazz and a little classical
Yes there are certain CDs in those genres that are considered classic for music and sound quality, but you probably know which ones those are. If not search this and other forums for Best Classic Rock CDs, etc.or just ask for examples of those and you’ll probably get a bunch of suggestions. People like to give their favorites a shout out.
just wasn't sure if there were particular labels or anything to focus on or if it was just as random as vinyl
Yeah, it's just as random.
