How Did You Know? - {Day 4}

We're back with another 5-day trivia hunt!

To remind you of the rules: Every day this week, I'll be presenting a specific challenge. Your job: come up with the answers and hold onto them! Why? Because on Friday, you'll need them to solve a short puzzle. The first person to email in the correct answers and successfully show how you arrived at them (thus the title: How Did You Know?) wins a choice of any t-shirt and book from our store.

As with previous How Did You Know? posts, comments have been turned off, but I definitely encourage you to work in teams. Last month's winner was the team of Bill Pearson and Adam Constable, who I know benefitted greatly from e-mailing each other throughout the week. So write your friends, send around each daily challenge, conspire, work together, whatever it takes to make sure you're armed with the right answers going into Friday's puzzle.

If you missed yesterday's challenge, it can be found over here. Monday's is sitting right here, and Tuesday's is right over here.

If you answered the last question of yesterday's challenge correctly, you've got a huge head start for today's challenge. On the next pages you'll find five album covers. Name the albums and the artists and be sure to check back tomorrow at noon EDT for the final puzzle.
