nah, tupac wasnt overated, he was 10 years ahead of his time.
Listen to other emcee's from his age,
Who insteada Dre an Biggie still have as much impact on todays hip hop culture.

Even today his shit dont sound old school.
As far as over rated goes I think Snoop fall's in that category,
As far as his stuff today goes, Drop it Like its Hot is plain garbage.
And I hate neptune beats. Way Over rated.
