How Do You Organize Your Music?

I keep all my regularly listened to audio files in one folder (My Audio). From there the trend is file_type\artist\[year] album. So for example,
C:\My Audio\1 mp3\Cut Copy\[2008] In Ghost Colours

I order By genre and What is in my ipod now

/Music HDD/Different Genres/Date/Alphabetic

order by genre (house,hip-hop,dance...)

I don't have much music in my PC. I use spotify so everything I have I have put in one folder.

I put all songs into itunes, and then I delete whenever I hear a bad song... Have just about 25gb to go, had about 250gb in the beginning

On two partitions, one with some folder with categories, other one for sort.

i have a partition only 4 that... so ... is not so hard

I organize by HDD>Artist>Album

If I was to start all over again though, I'd also most probably choose to sort by Genre, but I've downloaded way too much to try and organize it all again.

sort by artist =)
