G'day Kevin!
I know how you feel.
Realistically, only a brief introduction in English should be required at the advanced level.
Anyone still crying out for English at the advanced level is either kidding themselves, or needs to leave the English "crutch" behind.
IN the meantime here is what you do:
Using an audio editing program (I use
Audacity ) strip away the intro, save the file again as an mp3, and be on your way. Yeah I know it's an unnecessary pain the keester to have to edit each and every one of these files, but at least you won't have to listen to the same introduction OVER and OVER and OVER when listening to your collection while driving, or hiking with the mp3 player blaring in your ears. I don't think these people understand how long and annoying that English introduction is when listening to 100 lessons back-to-back on a long drive.
By the way, if you change your bookmark to
