disabling automatic tag

[Hika-Chan]

Hi!
maybe this question been asked previously... I found nothing
Winamp keeps changing my MP3 tags, so now I've got mixed titles (for example if I have song A by artist 1, song B by artist 2, song C by artist 3, one of them becomes song B by artist 1...)

Can someone tell me how to resolve this. I don't want my songs to be renamed automatically.

Thanks in advance!
