It appears that how good you are at singing is not really a matter but your taste in music can be.
Based on what kind of music you like, you might reveal TMI (too much information) about yourself to other people.
Theses are some from the article ‘What Your Taste In Music Says About You On A Date’ on HowAboutWe.
The Cure: You fall in love WAY too easily.
Beyonce: You’re sweet, but not a pushover.
Britney Spears: If you’re a gay guy or a woman, you’re normal. If you’re a straight guy, you’re trying to get laid.
Lil’ Wayne: You’re crazy. And kind of awesome.
Tool: You’re either really smart or really dumb.
The Beatles: Eh. Who knows.
