The first cassette I bought was probably Garth Brooks "The Chase".
The first CD I owned was Hope, a Hugh Masekela album with Grazing in the Grass and Bring Him Back Home on it.
The first CD I ever BOUGHT was Sgt Pepper's Lonely Hearts Club Band.
I've only bought a handful of physical CD's since then, probably less than six: Audioslave's self titled release, Beatles White Album, Beastie Boys "The Mix Up", and Fergilicious and FutureSex/LoveSounds for a road trip--everything else has been digital.
