Mos Def-BOB (Probably my favorite album of all of these. I still listen to it quite a bit) The Roots-Things Fall Apart (Still listen to certain songs) Pharoahe Monch-Internal Affairs (Still love this album) Dr. Dre-2001 (Still listen to it pretty often) Kurupt-The Streets Is A Mutha (I still listen to about half of this album) Public Enemy-There’s a Poison Goin On (Good late career PE album. I don't listen to it very often but it's a quality) GZA-Beneath The Surface (I loved it at the time but I rarely listen to this album) Tash-Rap Life (I haven't listened to this in a while) DMX-And Then There Was X (I almost never listen to this album) Soundbombing II (Compilation or not this album still bangs to this day)
Of these albums I'd say I still listen to about half of these and keep physical copies (vinyl and/or CD) of 5 of them.
