This is brilliant, more info at places like this:

I was brought up on The NME and the rock press and love left-field bands and I've always felt Billie (and her brother) fit comfortably into that tradition despite (or partly because of) their terrific pop sheen.

Great talent at a very young age; this next decade will be hers.

“...which begins with the singer’s original video for the song and, with the help of AI, has synced up thousands of covers...”

Isn’t this just a timestamp sync for certain search parameters? What has artificial intelligence got to do with this?

It could be a buzzword but I think it'd be fair to assume that different covers of the same song are slightly out of sync at different points. So the algorithm (AI or not) would look for signature beats in the original and match them with beats in a close range in the other songs.

I mostly got videos with the original song or overlaid at least. I am curious how well it could snyc actual 'covers'.

I would bet it's using NLP (AI) and looking for lyric matches based on the captions. You could likely make a cover with an incorrect beat but the same lyrics and the AI would match to it.

I bet not. I've been doing NLP for just a few months but my experience is that its fickle at best. Especially with a song that is so repetitive you'd be looking for (n) instance of (n) words.

Also, most of these videos arn't going to have human transcribed lyrics which would further increase the difficulty.

Why not just take all the data they have and throw it into a model to predict time.

On second run it looks like you're right. They have categories that have no lyrics at all.

These days "with the help of computers" doesn't have the same cachet. I did notice that the videos tend to follow instruments and styles. So it may be a bit more than just temporal synchronization.
