How Did You Know? - {day 5}

If you've made it this far, I commend you! One more puzzle to solve and you're home free. First one to send in the correct answer to the challenge below, along with the correct answers found all along the path this week, AND, the logic behind "˜em (which is to say: HOW DID YOU KNOW?), gets a pick of any t-shirt and book from our store.
As with last month, we're also adding some special prizes this time around for those who come really close, but don't get all the answers in time. We've previously awarded some shirts and books to a couple contestants who impressed us with charts, diagrams, and other complex methods of recording and organizing the clues/answers. So we'll be on the lookout for the creative among you, as well. This is all to say: it pays to play whether you nab the grand prize or not.
And remember, we're also giving away a really big, sa-weeet prize to any winning contestant who can defend the title three months in a row. Details on that as they develop, if they develop. (Avery Dale, Ken Laskowski and Colin Utley are our current champions. You can read about them here.)

If you missed Monday, Tuesday, Wednesday or Thursday's challenges, there might still be time to solve them all. No one knows how long it'll take for one of you trivia junkies to nail down the whole megillah, so make haste, make haste. And now, on the next page, I present the final puzzle, drawing on all the answers you dug up along the trail.
Day 1: On Monday you were asked to look at different magazine covers. Only one magazine shares part of its title with the abbreviation of a country. What is that abbreviation? Day 3: On Wednesday you were asked to I.D. five well-known recording artists. The woman in the second clip got her start singing in what famous trio? When you have the name of the group, remove the article and the S pluralizing the second word and that's your answer for Day 3. Day 2: On Tuesday you were asked to identify seven songs. The second song is off an album that has a pun in the title. What is the real song the band is mocking with their album title? The last word of that real song title is your answer to Day 2. Day 4: On Thursday you were asked to find six movie/TV titles camouflaged. The first title is composed of two words. Remove the ing from the first word and that's your answer for Day 4. Day 5: You should now have enough information to complete the puzzle. N.B. Day 4 and Day 2 in the graphic above were accidentally switched. So Day 4 should be where Day 2 is, and vice-versa.Â
