Does anyone do it? This might be useful to learn new styles or finger drum your favorite tracks, and after knowing the drum part we could play the drums over the other stems.
After a quick research I came across this 2 websites. Quality is not perfect and sometimes bass and low piano notes do get mixed with the drums but I thinks it’s good enough to learn or write the drum part.
Example:
Drums extracted from:
There’s also this izotope plugin that does this!
It can be very useful and a lot of fun to create your own jam tracks from real songs. It’s something that students can do and at the same time something I cannot do because publishing anything copyrighted is not a smart thing to do, especially if it’s tied to your online business, which it obviously is in my case. So I personally try ands stick with orginal songs and songs from epidemic sound of which I have a license to use them legally 
So yeah, I will probably never provide any of these tracks to my students because I can’t, but I can recommend students to play along to original music and ‘create’ their own study material with tools like these!
I suppose that the Isotope plugin has a better quality right?
And of course I was suggesting the use of this tools strictly for studying purposes.
As for the release of cover versions on online platforms, it is actually very feasible nowadays. You just have to make sure to search and credit every single person involved in the song. You can search here the artist - https://secure.harryfox.com/songfile/public/publicsearch.jsp - and don’t forget to search also for the song writer that might be a different person.
I don’t remember correctly the whole process but I know that the National Music Producers Association is also involved in the process:

After the research is done, it is recommended to release your track under a distribution platform like distrokid because they will only accept to distribute the song if everything is legal.
If you want to get deep into this, I recommend you to listen to this podcast that has all the information available and the easiest way of doing it:
Also available on Spotify:
I found this info awesome when I found it. I hope you also do so
I’ve got the Isotope plugin (RX7) and have used it to make backing tracks for me to play along to. It’s not perfect but it is useful
Interesting. I think that doing a drum cover using some original stems does not exactly qualify as a “cover” though. Maybe a remix…
Yes! You’re right 
To be considered a covered you would need to record all the instruments yourself and not use any of the original material.
I know that there are websites that legally sell acapelas of known songs that you can use in remixes if you do things properly for the copyright owners. I haven’t search for the other stems.
I have to re-listen that podcast. I can’t remember if they covered remixes and mashups as well, but I have an idea they do.
Just an additional tool I used a few times (with multiple options for vocals, etc.): https://moises.ai/
