Q: Is this worthwhile downloading seems to do nothing but sort out Apple music?

Your choice entirely.

If you take a few moments to read some of the other posts, you won't go within 100 miles of 8.4.1

Yes the tiny amount of posts here about it are obviously a representation of the hundreds of millions who are happily using it. All our phones have been updated with no issue. So what specific issues are you referring to with 8.4.1 that would keep you 100 miles away from it?

Nothing noticeable on iPhone, but on iPad (mini 2) sometimes wakeup button reacts with a delay (about 1 sec.), and then screen auto-rotation does not work (requires to press sleep and wake-up again, then works OK).

So really a waste of space update. Unless you are into Apple music. Thanks for all you comments

Unless of course you take into account the security updates also included.

About the security content of iOS 8.4.1 - Apple Support

But as I said, your choice entirely. Personally these days I take full advantage of any security improvements, no matter how small, rather than fall prey to professional hackers.
