Lol no. DRM does not, and CAN NOT work for anything that doesn't require interaction(such as games). If you can listen to a song, you can also make a copy of it without any of the NFT information.

Yes. You can indeed make a copy without the NFT information. You would have to basically record it and save it as a separate file. That is completely possible.
But the question is, why would you do that?
Look at the Brave browser. They have created a model where you can watch ads and get paid for it. Or you can choose to not see ads at all, while using the system for free.
You can do that for example with music as well, where a group of people is paid if they listen to music that people want to advertise.
Or, rather than being paid for listening only, you buy the NFT, and based on how many people listen to it through your NFT, you get paid a fee. What would the incentive be to create an NFT-free copy of the file...?
In fact, such a concept already exists, albeit different than both options above, where you can listen to music for free without ads while musicians get paid...;

If you can listen for free anywhere you want, wherever you want, why would you want a copy that is NFT-free...?
Besides... Who still goes through the hassle of downloading 'pirated' songs, rather than using Spotify or using YouTube...? There are quite a few people I'm sure, but these services make it very easy to legally listen to everything you want, where creating an illegal copy becomes a hassle.
The point is that despite it being possible, if the incentive is not there to make an 'illegal' copy, people will simply stop doing it.
