To me it was like 02-07 because I discovered the internet and underground acts. The mainstream was becoming trash but I discovered a whole shytload of non-mainstream artists.
Slum Village had a mainstream hit which introduced me to him, but I got into eLZhi real heavy around this time. (His underground work)
I discovered Little Brother and 9th would go on to become one of my all-time fav producers while Phonte' would become one of my all-time fav rappers. I was downloading a new 9th Wonder instrumental daily. Today, I have hundreds of 9th Wonder instrumentals that I listen to very often.
I also got into Joe Budden, Papoose, Joell Ortiz, Saigon, Blu, Termanology, Cory Guns, etc in this timeframe also. I was buying their albums and mixtapes faithfully.
Talib's "Quality", Blu's "Below the Heavens", LB's "Chittlin Circuit" & "The Minstrel Show" , Slum Villages "05" & "Slum Village" album were a few of my fav albums of the time.
Hip-hop was really good around this time, matter of fact, I was MOST into around this time period.
