See also Mass-Add ISRCs for one application for the data that I could think of.
I know you can search on Google, but I’ll tell you that 1TB now costs $100.
I don’t know where you have this info from, but you can easily find storage for ~20$/TB
(example ST20000NM002C Seagate Exos 20TB 3.5" CMR 7.2K 6Gb/s SATA 256MB Cache Hard Drive | eBay )
Also, the only data currently available is metadata at 190GB.
I was looking for external and from official stores.
And SSD. 
Are there any 1200x1200 pixel artcovers?
@Deleted_Editor_2599073 There are 130196 album covers with a width of 1200px or more. But from my experience, Tidal, Apple Music or Youtube Music covers are usually better.
I just looked at it like you asked, and there are 0 artworks that are 1200x1200px
Someone needs to hack them.
And what are their maximum dimensions?
Ok, whatever the data represents is definitely not correct.
From my own experience, Spotify cover art caps out at 2000x2000px.
When looking at the dimensions, the most I get is 1280x720.
Tidal, Youtube Music and Apple Music cover arts are usually 3000x3000px, sometimes even larger.
Due to the process of adding cover art being manual, I would advise against using Spotify as primary source, since there are usually much better alternatives available, and fetching the raw images is not the bottleneck.
It’s always more than 500x500.
As I said: For some reason I currently do not understand, the dataset is not representative of what you can find on Spotify.
It has cover arts as small as 64x64, but they seem to just be smaller versions of bigger cover art.
Looking at only the biggest variant for each release, the smallest cover art I have found is just 170x170.
So for now this data dump is not useful for MB considering the artcovers.
It never really was useful for covers, given that the process of adding covers is a much more tedious process than retrieving the artwork in the first place, and given that there are better sources for artwork compared to Spotify
Apparently they have better IT specialists.
You should expect Spotify to lock down their API.
Personally… it could be a positive change since the quality of Spotify imports into MusicBrainz leaves a lot to be desired in my experience. (And the editors always blame the tools.) There are still many Spotify quirks that tools don’t or refuse to address to match artist intent and/or how the metadata is presented on other platforms with less weird style rules.
They definitely have it in their logs.
Though sometimes the best cover I could find was on Spotify and the others had worse.
Which are sometimes just upscaled lower resolution images.
Isn’t that link be considered piracy? I don’t think you should post that here.
The link itself is seemingly to a blog post which contains no infringing content (the whole domain is blocked in Belgium though, so I’m just checking based on an old archived version), and this was reported by large news sites at the time so it’s not exactly a secret. That said, let’s not post further links to this, other than the newsworthiness of it (which can be discussed this one time) we should certainly not promote it.

How so? Genuinely curious here on if I’m missing anything important
You should expect Spotify to lock down their API.
Your wish unfortunately is coming true…
