In September 2015, alt-rock godfathers R.E.M. blasted GOP candidate Donald Trump for using their 1987 hit "It's the End of the World as We Know It (And I Feel Fine)" during a rally.

Now, weeks out from Election Day, the band has joined up with Death Cab For Cutie, Aimee Mann, Jim James (of My Morning Jacket) and a slew of others for "30 Days, 30 Songs."

The project will unveil a new or previously unreleased song by one of the participating bands each day for the remaining 30 days through Election Day to "provide both motivation and soundtrack to doing the right thing these last few weeks before this most pivotal election."

The first song for the project is Death Cab For Cutie's "Million Dollar Loan," which Mashable wrote about on Monday.

Lest there's any doubt as to who the project supports in the election, the group says on the website, "As artists, we are united in our desire to speak out against the ignorant, divisive, and hateful campaign of Donald Trump."

On Tuesday, a new song by Aimee Mann, "Can't You Tell?" was shared as the project's second entry.

In a post about the song, Mann said the song is written from Donald Trump's perspective and takes the angle that maybe this whole surreal campaign was basically "a runaway train."

Said Mann, "my own feeling was that it wasn’t really the job itself he wanted, but the thrill of running and winning, and that maybe it had all gotten out of hand and was a runaway train that he couldn’t stop."

The project is an independent endeavor that features bestselling author Dave Eggers and Jordan Kurland, founder of Zeitgeist Artist Management (Death Cab, The New Pornographers), among its leaders. The group also ran "90 Days, 90 Reasons," a similar effort that backed Barack Obama's re-election effort in 2012.

Mashable has reached out to the organizers for more information and for a list of future artists.

Speaking to Paste Magazine, Eggers said he was inspired by seeing songs of artists that opposed Trump played before his rallies: "t occurred to me that this election would benefit from the timely resurrection of the political protest song."

Every song will also be added to the project's Spotify playlist, in case you want to listen to every song in one place.

The project is reminiscent of the 2004 Vote For Change effort — which included the aforementioned R.E.M., plus Bruce Springsteen, the Dixie Chicks, and Pearl Jam — that supported John Kerry in his bid to unseat then-incumbent president George W. Bush.

Proceeds from "30 Days, 30 Songs" will be donated to The Center for Popular Democracy.
