Re: The trouble is...
There's DRM on all the video services - the studios won't let them do it without.
But iTunes music hasn't had it since 2009, which was the point where I started to buy the odd album from them. Though often Amazon MP3 is cheaper, and bizarrely Amazon marketplace can be cheaper still if you buy a CD - you have a delay before it arrives, but then a lossless rip. Why none of the main download services offer lossless beats me.
However, Apple Music is a real mess: I'm not touching it because it isn't separate from your own library, and it has messed some people's stuff up royally, including replacing people's master copies with DRMed streaming copies. If you could subscribe without it interfering with your local library I might be interested for those times you might want to hear an album to decide if you want to buy it, but no way while I would be running the risk of it destroying my collection with its carefully edited metadata. If I ever feel the need for streaming, Spotify looks like the one to go for.
