There is another thread entitled "gettin technical" that even says what songs and at what frequency the box is tuned too.

 

If you like old school try any song off the Beastie Boys first album. Oops I said album. Now that's old school.........

 

Incubus - Under My Umbrella

...I know you said rap but... well lets face it, rap is boring, lame, overplayed, and overrated.

 

anything by westside connection is good

 

try Live-Secret Samadhi CD...Rattlesnake*track 1* Lakini's Juice*track 2* Ghost*track 5* Unsheathed*track 6*...Hero Psycho Dreamer*track 9* Freaks*track 10*

riding in my brother's 93 Ford Explorer...this stuff hits...hard...

 

sublime is great for bass. my friend has a crime mob cd that has some long tones too. it sounds great
