listen to 2pac, biggie, eazy-e and old nas if you like hip hop
This. I like Lil' Wanye alright, his lyrics are genius, but I honestly don't feel like a lot of it is coming from the heart. Old rap seems to be more genuine in my opinion.
Here are some of my favorite songs, these are some of the first things that came to mind. This is all rap, so if you youtube any of these songs, there will be foul language and the works.
Machine Gun Funk (The Notorious B.I.G)
All Eyez on Me (2pac)
Amerikas Most Wanted (2pac featuring Snoop Dogg)
Mary (Wax, 6-dimension has probably already linked to a bunch of his stuff)
New Crack (Wax)
Air Timpani (Wax)
One More Chance (Biggie again, the one off of Ready to Die, not Life after Death)
Microphone Murderer (Biggie again, I think this one is off of his demo tape)
Ah, basically everything Biggie has ever done. I'm rarely not listening to Ready to Die. Scrublife (Wax) is another album that I'd strongly recommend listening to, you can download it for free too.
I also like a lot of Bluegrass / Country stuff. Johnny Cash is the best. I also like Split-lip Rayfield, Yonder Mountain String Band, and The Gourds.
