Remote Streaming - worth it?

Early on, when I first setup my household LMS system, I set up remote streaming just to see it work.
I was able to get it to work. I used my laptop at the local sandwich shop as validation.
This was before smart phones and tablets.
I'm going to try and set it up again. This time will be to stream to my phone in the car and my tablet at various locations.
Pandora and iHeart is pretty good. But it's not the same as having my music collection available.

I'm sure I'm not the first to do this. so...

I'm curious about user experiences, good and bad, streaming their LMS to the car and beyond.

Thank you,

Randy
