Let's be real, the 70's and 80's produced some of the greatest songs ever. Songs that are nearly 40 years old are still sung by people of all ages. It doesn't matter if you were around during the 70's or the 80's, there's still a high chance that you know (almost) every word to many songs. Whether you're with a group of people at a party, in the car with friends or by yourself in the car and a hit from those decades comes on, it's kind of hard not to start jammin' your heart out. Although I can list hundreds of amazing songs, I listed my top 25 choices that instantly makes me want to scream the words to whether alone or at a party.
