Order files list by batch - batch-file

Question

I have a long list of individual songs not in folders just songs, and I'd like to move them to the folder of theire artist. the songs are in the following format
artist - songname.flac
I can store them in a list, and echo it, but splitting the artist and songname in 2 vars, I can't seem to figure out.
Could someone help me with the splitting (or if you want even with the rest of the script)
this is what I have so far:
#echo off
setlocal enabledelayedexpansion
set N=0
for %%i in (*) do (
set Files[!N!]=%%~ni
set /a N+=1
)
for /l %%x in (1,1,%N%) do echo.!Files[%%x]!
pause

Answer 1

set SOURCE=c:\temp\test
for /f "delims=-. tokens=1,2" %%i in ('dir /b "%SOURCE%\*.flac"') do echo Artist : %%i Song : %%j
update for full script (got to check if it works with space and special chars in path) :
#echo off
setlocal enabledelayedexpansion
set SOURCE=c:\temp\test
set DESTINATION=c:\temp\test
for /f "tokens=*" %%i in ('dir /b "%SOURCE%\*.flac"') do call :OrderThatMess "%%i"
:OrderThatMess
set NAME=%1
for /f "tokens=1,2 delims=-. " %%j in (%1) do (
set ARTIST=%%j
set TITLE=%%k
if not exist "%DESTINATION%\%ARTIST%" (md "%DESTINATION%\%ARTIST%" )
copy %SOURCE%\%NAME% "%DESTINATION%\%ARTIST%\%TITLE%.flac"
)

Answer 2

#echo OFF &SETLOCAL ENABLEDELAYEDEXPANSION
for %%i in (*.flac) do (
set /a N+=1
FOR /f "tokens=1,2 delims=- " %%o IN ("%%~ni") DO (
set "FilesA[!N!]=%%~o"
set "FilesB[!N!]=%%~p"
)
)
for /l %%x in (1,1,%N%) do echo(!FilesA[%%x]! !filesB[%%x]!

Answer 3

Thanks for the answers ;) Thanks to Kayasax I fixed it
here is the full code:
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set SOURCE=C:\music\folder\with\files\
for /f "tokens=1,2 delims=-" %%i in ('dir /b "%SOURCE%\*.flac"') do (
set "folder=%%i"
IF NOT EXIST "%SOURCE%\%%i" (
mkdir "%%i"
)
move "%SOURCE%\%%i-%%j" "%SOURCE%\!folder:~0, -1!\%%i-%%j"
)
pause
