I need help with transferring music onto my Nokia N95?

I have a Nokia N95 and I've downloaded Nokia PC Suite and everything but I'm having problems transferring songs onto my phone. I've transferred music before and it worked but now when I try it automatically speeds up the songs. I don't know why! =[ Can anyone help? Thanks

Dont use PC Suit this time.
just copy the songs from your computer and paste it where the all music files are placed in your phone.
