As we reported last month, Washington state musicians and music-industry insiders are rallying for gay marriage in a big way. Music for Marriage Equality launched in early June with a get-out-the-vote campaign— Vote Yes on Referendum 74 —that drew support from everyone from Pearl Jam to Death Cab for Cutie, Mudhoney to Macklemore. In addition to videos in support of gay marriage on the MME website (much like Dan Savage’s It Gets Better Project), some musicians are also going to work for the cause.

Rapper Macklemore and DJ-producer Ryan Lewis just released a new single, “Same Love” (feat. Mary Lambert) with MME and Sub Pop; it’s on sale now on iTunes and Amazon. All proceeds from the $.99 track support marriage equality in Washington state, but it’s also a sign of good things to come for Macklemore and Lewis. The duo drops its debut album The Heist October 9 and kicks off a West Coast tour at Portland’s Crystal Ballroom (Oct 11) and WaMu Theater in Seattle (Oct 12, tickets are on sale now).

If you read Culture Fiend regularly, you already know I love me some Macklemore, and what I like even better is how thoughtfully he reacts to each rap. In this blog post he talks about the inspiration for ‘Same Love,’ which is, in part, a nod to his uncle, who’s long been in a same-sex relationship. Or you can just listen to the opening lines to get the idea. He’s not one for metaphor.

I used to think I was gay because I could draw
my uncle was
and I kept my room straight.
I told my mom
tears rushing down my face
and she’s like Ben,
you’ve liked girls since before pre-K.
Guess she had a point didn’t she.
Bunch of stereotypes all in my head…
