Thanks, just updated the spreadsheet with some of these.
I got the title for I Must Be Lonely from this page on genius for their first EP https://genius.com/albums/Motherland/Motherland-1 and I’m not totally sure what it is either and haven’t been able to find it anywhere on YouTube or soundcloud. I’ve changed it to unheard on the spreadsheet for now but I might remove it. I’m having trouble finding a source for the tracklisting of this EP to confirm that the song even exists. Ooops was released as Sfire7, and Sophie’s involvement with Slip N Slide has been pretty contentious since it’s not very different from the released version which she doesn’t have a credit for. I don’t think we’ll ever 100% get confirmation that she was on the demo but I have added it, for some reason I just feel like she might be on it and if I remember correctly it did leak with her name in the filename.
Miami is only produced by The Invisible Men as far as I’ve been able to find but it’s pretty difficult to confirm anything with unreleased music. My understanding is that the only version of The Party’s Never Over we have currently is produced by Lotus IV but there have always been rumours of a Sophie and A.G. Cook produced version. Some (if not all) of the snippets referred to as being Sophie produced are actually just the song mixed with an Umru and A.G Cook collaboration named Ice Cakes. Those snippets may be a fan mashup or a real demo of the song but Sophie isn’t on them, though she might have a version of the song. I’m not sure what the situation really is with that song.
I heard someone once on the PC Music say that LAZ3R TAG was a Sophie remix/remake of an Autechre song or maybe just interpolated an Autechre song, but I can’t remember the song that they linked and it’s hard to Google now after the Autechre remix of Bipp. Which reminds me if I remember correctly in one of the Sophie discords a few years ago Art Fair was identified as a Sophie remix of an instrumental song by another artist that I can’t remember the name of. This is the track I’m talking about for reference https://m.soundcloud.com/user-790665783/sophie-art-fair I’m having trouble finding anything out about that though if anyone has any information about it.
