The one song everyone is downloading to support marriage equality.

If you happened to check the iTunes charts last night, you’d be forgiven for thinking there was some kind of glitch. In the number one spot was a song from 2012.

Macklemore, Same Love.

Odd, given the Seattle-based rapper has new music out at the moment, via his album GEMINI. But not if you’ve been following the ‘controversy’ over his NRL grand final show this weekend.

The whole thing was stirred up this week when former rugby league player Tony Wall railed against Macklemore’s plan to perform the Grammy-nominated song on Sunday night; a song that was recorded in aid of the marriage equality referendum in the US state of Washington five years ago.

To voice his concern, Wall launched a Change.org petition in which he called for NRL boss Todd Greenberg to stop “imposing such a bold political stance on its fans”.

“As a former NRL player married for the past 12 years to my wife and with five children, I respectfully ask that you reconsider the NRL’s position and remove LGBTIQ politics out of the awesome sport of Rugby League,” he wrote.

Speaking to 2GB radio's Steve Price, Greenberg said the code was "very comfortable" with the message the rapper would be sending via his music.

“We’ve made it pretty clear that we’re an inclusive game," he said.

“It’ll be a little hypocritical of us to have inclusiveness as one of our values and not actually deliver on it.

"We’ve made our position pretty clear. I don’t expect everyone to agree with that and I understand that.”
