Early Friday morning, Tyler, The Creatordropped off his latest album IGOR, a project that is unlike any other that he’s released to date. The R&B, jazz, funk, and gospel influences can be heard throughout, and even Tyler himself warned fans not to listen to IGOR with preconceived notions. “Igor. This is not Bastard. This is not Goblin. This is not Wolf. This is not Cherry Bomb. This is not Flower Boy. This is Igor. Pronounced EEE-GORE,” he wrote on an image uploaded to Instagram.

Don’t go into this expecting a rap album,” Tyler continued. “Don’t go into this expecting any album. Just go. Jump into it. I believe the first listen works best all the way through, no skips. Front to back. No distractions either. No checking your phone no watching tv no holding convo, full attn towards the sounds where you can form your own opinion and feelings towards the album.”

The album is a feature-heavy project that boasts big-time music industry names, but in the near 24 hours since the record dropped, IGOR has been at the center of a mystery. On streaming services like Apple Music, Spotify, or Tidal, IGOR‘s tracklist doesn’t overtly show who’s featured on the album. However, if you take a look on Genius’ lyrics pages for each one of the tracks, contributors to each song are listed. However, Tidal’s credits for each song doesn’t exactly align with Genius’ listings.

So the question remains: who’s really featured on this record? According to Genius, this is the tracklisting and additional vocals:

1. IGOR’S THEME ft. Lil Uzi Vert & Kali Uchis
2. EARFQUAKE ft. Charlie Wilson, Devonté Hynes, & Playboi Carti
3. I THINK ft. Solange & Kali Uchis
4. EXACTLY WHAT YOU RUN FROM YOU END UP CHASING ft. Jerrod Charmichael
5. RUNNING OUT OF TIME ft. Frank Ocean
6. NEW MAGIC WAND ft. ScHoolboy Q, Jerrod Carmichael, A$AP Rocky & Santigold
7. A BOY IS A GUN
8. PUPPET ft. Kanye West
9. WHAT’S GOOD
10. GONE, GONE / THANK YOU ft. Mild High Club & King Krule
11. I DON’T LOVE YOU ANYMORE ft. Solange
12. ARE WE STILL FRIENDS ft. Pharrell Williams

N.E.R.D. legend Pharrell Williams shared the IGOR cover art on Instagram as he hyped the album, and Tyler commented, “WOW DAD AND THANKS FOR YOU CONTRIBUTIONS TO IT.” For now, we’re going to go with what we know as fans continue to speculate about who’s who on IGOR.
