tips on making a playlist with media player?

[WhoaitsZ]

i'm using windows media player 9 and for the life of me am having a rediculously difficult time getting it to read some files correctly. case in point:

i had a audio book chapter 7 folder.

i had to change the mp3s around cuz chapter 7 was actually chapter 8, 8 was 7.

so, when i renamed it all i went to the make new playlist and went to chapter 7 again and started.... it was playing the same mp3s as before.

so i did 'add new folder'. since i had edited it and i did thus and did make new playlist and went to chapter 7 annnnndddd..... same thing happened again.

i've done this like 8 times. i'm thoroughly confused.

how do i delete some of the options on my 'add group/artists'? a lot of options there i'll never wanna use.
