As someone who strictly makes money online, I have to work at many different websites to make a full time income. One of my favorite websites I earn money with is called Slicethepie.com. This is a pretty basic company to work for. All you need is a Paypal account to get started.
You will be presented with music clips and full songs that are mostly Top 40 hits. You must listen to the song clip for atleast 90 seconds before submitting your review. You can type your review while you wait for your countdown to end. Once you submit your review you will be shown the amount you were just paid. I have been averaging $0.09 per review but you can make much more the longer you review. Your review should be 3-4 sentences describing the positive or negative in a song. It is very quick and simple.
You can sign up with your facebook page but if you do, be sure your email address associated with your facebook page is the same as your Paypal account. I made the mistake of having different email addresses and had to wait almost 2 weeks to get my first payout. You can cash out once you hit $10, which is not hard to do.
