In response, here's my list. The list is just stuff that's on my playlist currently, not all-encompassing (if you want that, just look at Wikipedia). My taste in music isn't that expansive when it comes to LA.
Note: Would like to see other lists, rather than just "the" list.
First off, the songs that I like that I'm not sure too many other people like:
Bambu - Where You From
Michelle Shocked - Come a Long Way
Bambu - Take the 5
The Aggrolites - Reggae Hit LA
Murs - LA
Then the obvious:
2Pac - To Live in Die in LA
Sublime - April 26, 1992
Then there are songs that have an LA feel to it:
Montell Jordan - This Is How We Do It
Coolio - Fantastic Voyage
Dumbfoundead - Jam Session
Then there are some artists who don't have an LA-hit but "feel" kinda LA. And by "LA", I mean multi-disciplined, multi-cultural, multilingual, multi-talented, stuff that hits you in multiple ways.
Aceyalone - Everything Changes
Bermudas - No Voy a Trabajar
Mexican Institute of Sound - El Microfono
