Sitting in my room listening to my lime green iPod Nano in middle school, I can assure you that my priorities included knowing all the cool songs and each lyric to them. There's a reason why music appeals to almost every person of all ages in a positive way. For some, just a few lyrics to a song can lighten your mood, relate to something you're going through, or transport you years back in time, to a moment you'll never forget.

Here are some songs that take us up to 10 years back in time, and many that I'm sure you've forgotten about by now. The music itself is already so different now compared to these "oldies" if you would even consider them that. I hope these bring back just as great memories for you as they did for me. Needless to say, I will never get sick of hearing these songs. Reminisce, remember, and enjoy. You can thank me later.
