There's nothing quite like nostalgia. Just about anything can trigger a memory of your younger years, whether it's a picture, a fire ’fit or, as often happens, a song. Music, especially hip-hop, is connected so close to memory that the two go hand in hand; the songs you liked at a certain age serve as the soundtrack for plenty of memories. Adulting is great (OK, sometimes it sucks), but looking back to the carefree days of being a teenager is special. Luckily for hip-hop fans, the era where songs of yesteryear are being reworked and presented in a brand new fashion is happening now. There are plenty of rap tracks over the last few years that sample these songs from the past, and it's time to highlight some of the best.
