Depends on the bands. Led Zep and Chic? Golden, no issues here, you're living your best life. Nickleback and Black Lace? You have a serious problem and may need to seek medical attention for terminally bad taste.
Wow! You mean other people besides me put Chic and Led Zeppelin on the same playlist? I never met anyone irl that does this except myself. I don’t even need booze to do this. I just do it all the time.
