In no particular order:

1.) "What they do" The Roots.
It's a milestone song for me in terms of falling in love with hip hop.
I vividly remember seeing the vid for the first time ( I was 14 ).

2.) "Cherchez La Ghost" Ghostface, U-god and Madame Majestic
Makes me dance my ass off. Every time.

3.) "Do it now" Mos and Busta.
Love the chorus, Mos' flow on his second verse and the beat.

4.) "Rebirth of Slick" Digable Planets.
Timeless. Will never NOT be in rotation imo.

5.) "3 The hard way" Bahamadia, K-swift and Mecca star
Out of control writing and delivery.
