I'm sorry if i dont recommend anything to anyone, but i'm starting to dig hip hop only now. I'm looking for very lighthearted simple stuff, maybe with a touch of sweet sweet melancholy. Something like this:
This song talks about the artist's childhoold, but with nothing sad... i'd say you can perceive some nostalgia but it's never really expressed in words (Example: "I miss the old days, they were so good

")
I mostly listen to music for the music itself, i rarely focus on the lyrics, keep that in mind. Obviously lighthearted, simple and even "makes-you-want-to-smile" lyrics are preferred.
