*updated playlists on the 22nd of September 2012
The list is far from complete since a lot of tracks can't be found in Spotify (yet). But I feel they're still worth sharing:
Weeds Season 1 tracks
Weeds Season 2 tracks
Weeds Season 3 tracks
Weeds Season 4 tracks
Weeds Season 5 tracks
Weeds Season 6 tracks
Weeds Season 7 tracks (Updated 22nd of September 2012) help me add more tracks.
Weeds Season 8 tracks (Created 22nd of September 2012)
I've also compiled them all in one list so you can choose:
Weeds all tracks
Also check out the spotify playlist for The Wire (check The Wire post link in the sidebar).
Showtime itself has an oversight and a lot of playable music
