@echo off

 for /f "tokens=1,2 delims=-. " %%i in ( "%%a" ) do ( ren "%%a" "%%j - %%i.mp3" )
 )

@echo off
setlocal EnableDelayedExpansion  
for /f "tokens=1,2 delims=-." %%a in ( 'dir /b *.mp3' ) do ( 
set vara=%%a
if "!vara:~0,1!"==" " set vara=!vara:~1!
if "!vara:~-1!"==" " set vara=!vara:~0,-1!
set varb=%%b
if "!varb:~0,1!"==" " set varb=!varb:~1!
if "!varb:~-1!"==" " set varb=!varb:~0,-1!
ren "%%a-%%b.mp3" "!varb! - !vara!.mp3"
