Need assistance with adding files to play list

[Learning]

Hello -  I'm new to AIMP and new to tablets too, actually.  Have no one to help me; learning on my own, which is challenging. 

I just purchased a Samsung Galaxy Tab A (2016), model# SM-T280, Android version 5.1.1

I added all of my music files from my PC via microSD card.  Figured out that I needed an app to play them (YES, I am just that new to all of this.)

I selected AIMP because I liked the reviews I read about it.

SO, I've downloaded AIMP, v. 2.90, Build 844, but it doesn't seem to be working for me the way I understand that it should work.  Maybe my experience will be useful feedback for you as well as help me to be able to use your apparently beautiful product.

The challenge I have (aside from not having a User Guide) is getting AIMP to import the music files from my microSD card.

I have figured out how to go to that card, and can see all of my files.  My files are arranged in this manner:

a) Rock n Roll
b) Space Music
c) Jazz
etc.

And then under each of these categories, each artist has a folder....and each recording has its own folder. 

I see how to open the subfolders.  But there is where it seems to break down for me.

I check the box beside the recording I want to draw over, and then click on the "check mark" icon in the lower right of the screen.  But nothing happens.

I've tried importing an entire genre at one time (ex., "Space Music"); I've tried one artist at a time; I've tried one recording at a time.

Oddly...for no apparent reason that I can figure out...AIMP has pulled over a total of 2 recordings, and it did this when I was asking it to pull something else other than what it brought over.  The first time, I was trying to bring over the entire genre at one time...and it just picked one recording by Buckethead (ironically, "Electric Tears"...the universe has a sense of humor!)  The next time, I was trying to bring over only one artist's recordings...Jonn Sierrie...and AIMP selected 1 of his recordings...ignoring the others.  Now I can't seem to get it to bring over anything else.

So, I do have a few examples to play with, and I have to say, I really love the interface.  Beautiful! I'd like to continue to use AIMP but I'm not sure why I can't get all of my data to move to it.  I have a total of about 16.1 GB of music data files.  I'd read that AIMP could pull it all over at once, but clearly, that's not what I've been able to achieve.

If you can assist me, I'd be most grateful.  And if not...like, if my device isn't fully compatible with AIMP...please let me know and I'll sadly choose another music app.  Hope not but if that's how it is, I'll just have to accept it.

Thank you much in advance for any help you can give to me!  :-)

Hello,

The challenge I have (aside from not having a User Guide) is getting AIMP to import the music files from my microSD card.

Whats was difficult? AIMP provides few hints how to add music at first time. Yes, I know, AIMP is old-school audio player, it does not have a music library like other modern players have, but you have a full control under your music and actions.

I check the box beside the recording I want to draw over, and then click on the "check mark" icon in the lower right of the screen.  But nothing happens.

Hm, its strange. Does player show your music files in File Adding Dialog or just a folders? What format of your music files?
