I wondered about that, too. It's confusing; and I spent some time Googling trying to find out for sure, without much luck. On Tommy's IG, people seem to think it's his album; and on the Richie sites, they think it's Richie's. The only thing I could find was in the podcast Tommy did with his new wife. He said his album is gonna drop the end of April or the first of May.
I wouldn't think he would still be recording new material if it's scheduled to be released in 3 or 4 weeks, would he? (But then again, he also said he hasn't decided on a name for the album, either. So who knows...)
I'm with the Captain, though. I'm pretty sure that's Richie singing. And as much of a Hendrix fan as Richie is, the lyric, "Excuse me while I kiss the sky" makes me willing to bet it's a Richie song.
But that's all I got; and I've been wrong before, too.
