Why not just subscribe to a streaming service like Youtube Music? I gave up ripping CDs and copying MP3s to my phones back after the S7 and just stream everything now.
Streaming isn't effective for everyone. These are old debates.
--Apart from cost (why exactly do I have to pay? The local directory is free), it is hardly comprehensive if you have broad tastes (I also like lots of classical and French language and I'll bet you some things won't be there), but that's hardly the big issue.

Most importantly--streaming doesn't actually work everywhere. I travel a lot. I've greatly enjoyed streaming while driving around remote areas of Virginia. That is, I enjoyed it cutting out constantly, but not actually working well. Then, there's international travel. Streaming doesn't work so well on 3g on the streets of Mont St. Michel. Airplanes are a flip of a coin. Sometimes there is a good answer and a cost effective one, sometimes not.
Maybe one day we will have universal success in streaming access for nominal fees--in fact, I predict we will--but that day is not today. The easiest and simplest thing is to have my data local.
--Then, there is the situation I just mentioned. Every phone setup is going to be hours more now for me with every new upgrade. Which is another good reason not to upgrade often. The SD card just popped in. All set up in seconds. 90 seconds to pop a card in, or buy a streaming service so Samsung can continue to keep selling me the same old hard drive space with every upgrade and I can pay a streaming service to deliver music I already own. Hard choice.

Oh, and now I'm spending hours backing up the internal HDD of the phone for data. I never had to do that before either. The SD card was the backup.
--Then, I wonder how many will choose modest storage thinking they don't need much--maybe they have streaming--and then find with the super HD video and hi res pictures, it is hard for them to store much and have much room left.
I had everything worked out just fine until Samsung decided to get greedy. As a result, I upgraded to a 23 rather than a 22, my normal every-two cycle. I expect my next upgrade will be to a 27 rather than a 25. Unless SD cards come back. I hope that works for Samsung. It's not working for me and I will be looking to expanding upgrade cycles as much as I can. I'd also be interested in any competitor that brought the cards back. There was a time when Samsung made a splash doing things like that. I guess it's old and tired now, too busy imitating Apple to care.
