How to exclude ringtone from showing in Nokia Music Player

you will firstly need either Y-Browser or X-plore.

Then use for example x-plore to navigate to your mp3 song. then select the file and go to Menu, File, Attribute. Check the Hidden and System checkbox. and press on OK. If you use Y-Browser, then its almost the same, just navigate to your mp3 song, then go to Options, File, Attributes, and change System and Hidden to Yes. see below for more ways!

OR

you can create a folder in your memory card, by going to E:\ then going to Menu, Make Dir, and type in the new folder name. press on OK to confirm. then do the same thing as above, select the directory, then go to Menu, File, Attribute, then check the Hidden and System checkbox and press on OK to confirm. This way, you can put multiple ringtones in this folder, and you don't need to select each ringtone one by one to set the attribute. i guess its faster?
for Y-Browser, go to Options, File, Attributes, and change System and Hidden to Yes.

then go to your Music Library, and go to Options, Refresh Library. the ringtone will be missing from your Music Library. However, it will still be available for selection as a ringtone...
