How accurate was René?

TL;DR pretty accurate but phonetic errors.

So Poor Christmas from The Face could be something that just sounds like that. For the other unknown song on the tape Trip to Rio, I'm convinced that 'Base Bizarre' is probably more like Balthasar.

But here was his track record:

"Say (It's Not True)" attributed by René to "Steven's Café" was identified in 2021 as Say by Steven Café. The artist and title were an almost match.

"Kiss Me" attributed to Stac's was identified as "Beautiful" by Con Act. The title and artist were initially thought not a match, but later noted that Con Act also went by the name "Stac's".

"Indian Summer" with no artist listed was identified in 2020 as "Indian Summer" by Friedemann. The title was a match, René just hadn't caught the artist.

"Dreamtime Lover" attributed by René to "Q. Tango Mouse" was identified in 2020 as "Dreamtime Lover" by "Quango Mouse". The title and artist were a match aside from phonetic spelling.

"Different" attributed to The Dead Adare was identified in 2013 as "Different by" The Dead Adair. The title was a match and the artist differed slightly only in spelling.

"Come On I'm Telling You" attributed to No was ident as "Comment Allez Vous" by No.

So similar sounds are very possible
