walkman playlist

In the walkman player, you can search the song in your memory card by searching the "tracks" button. But, it will search all the .mp3 in the phone that is displayed in the sounds of file manage.In my memory card there are about 200 songs in it. If I create a playlist for it, it will cost lots of time to select.
Is there any method that the player only search the mp3 in the memory?(My songs is put under memory cad/MP3.)

Put the mp3 that you dont want in your playlist in the ringtone folder

OK! I try this

ou can this with winamp, too

then how to do then?

Yea, how?

My method is to make new folder in memorycard/MP3, like memory cad/MP3/music, and then in playlist creator I just mark memory cad/MP3/music folder and add it. I hope this will help you. And sorry for my English, if there is some mistakes.
