Perhaps you noticed already putting a ringtone in your phones storage or sd-card makes it only visible in the general 'music' tab(as far as i know). To surch your ringtone out of your 1000 music files had to make you convert the name of your ringtone adding a # symbol or something else to find it between the mass...
In fact when you put f.e. a ringtone in Ringtones folder of your internal storage it makes the ringtone visible in BLUE under your 'music' tab.
When you add a ringtone under a folder like ringtones you created on your SD card it makes the ringtone visible in BLACK under your 'music' tab.
For me this was not an option to 'search' my ringstones and other stuff under a general music tab. Instead i wanted them to be visible on the right place as it should be. As you know you have to be rooted to put ringtones (...) in system/media/audio/ringtones...BUT as i never had to put ringtones in SYSTEM before this time there was a little problem : in SYSTEM they did play in my explorer but they didn't play when i had to select them under the 'ringtone' tab when f.e. selecting a specific ringtone for your phone. They just gave a 'faulty' tone....
It took me a while before i saw that all the A7 files under ringtones (e.o) are rw-r-r- and mine were rw-rw-
On my other phones this never gave me a problem because i could just put any ringtones in a folder of my sd-card. Here it's different and not-user-friendly.
So, solution is very obvious, just use Root Explorer and change permissions of your ringtones to rw-r-r
You can select them all togheter and change them. (In Solid explorer f.e. you can only change one at a time. Therefore i recommend Root Explorer.)
After that they are visible and playable under 'ringtones' tab (...)
I just wanted to share this for rooted (and non-rooted) users when they encounter some problems to import ringtones (...) in system
