1 - I really don't know that much about the Android OS (I only came to it in order to use MS) but it seems to me that each manufacturer introduces its own little modifications to the basic coding. With (say) Windows, you simply acquire the OS and load it into your computer, in the knowledge that it will run as you would expect.

From personal experience, I found that you can't do this with Android, each version appears to be tailored to the hardware it's intended to run on. Ergo, it's possible that your file limitation is because of this .... and explain why I don't have the limitation.

I guess Mike knows much more about this stuff, so let's see what he has to say.

2 - 'Songs' was my first thought, but then I asked myself, why?

The songs are already in alphabetical order and if you use Companion (I think most users do) then it's a simple thing to scroll through the list to see if you already have a duplicate copy, different arrangement, etc.
