Filenaming with songs with the same title

Because I love hearing alternative versions and live versions of songs I often have a lot of songs with the same name. So when I try to use Tag - Filename on the songs where the title is the same then it comes up with:

File "D:\Blah blah.ogg" cannot be renamed to "D:\Blah blah.ogg".
Cannot create a file when that file already exists.

Basically what I'm asking for is if there is a code where it would just add a number after the song if there is more than one, eg:

The Car Song.ogg
The Car Song 1.ogg
The Car Song 2.ogg
The Car Song 3.ogg
....

Any help is appreciated.

Yup, use %_counter% for sequential numbering.
