I didn't really need to do this, but I did so anyway. The metadata said all the songs by Devcool are 192kbps, which is the max output of Suno AI. The spectrograms reflect that. (A 19kHz max frequency is indicative of a bitrate of 192kbps, regaurdless of what the metadata says.) In fact, many of the spectrograms show even worse bitrates, which Suno AI also often spits out. They just didn't properly cherry pick the generations for the best ones.
Here is an example:
This one doesn't even breach the 16kHz threshold, which equates to a 128kbps bitrate.
Another example:
This one has some fuzz that peaks out to 19kHz, but the majority of the song has a max frequency of about 17kHz.
I uploaded the rest of the spectrograms to my file dump (download and unzip it):

Also, anyone who knows what Suno (and AI generated music in general) sounds like can easilly tell that these songs by Devcool were made by a generative model. "Everlasting Fantasy" is really quiet for the majority of it, before finishing off with some strange sounding string instruments. Or maybe it's horns. You can't really tell because it's all just an artifact-filled mess. "Run Away" hits all the crusty high tones right off the bat. Same with "Steve Harvey" and a couple others. All of the songs have percussion that sound strange at best. I don't know why these songs were restored, but I'm near certain they're AI generated and should be looked at thouroughly by a mod again. @ADR3-N, I know you're very familiar with AI, can you take a look at Devcool?
The metadata, spectrogram analysis, and the artifacts the songs have all point to Suno AI.
Thanks,

P.S. This is unrelated to Devcool, but look at this song too.
