I bought recently the Vol. 10 and have to say, you can not get more for your money if you like this kind of music. I stand on the special Sound of Disco Boys. You do it in their very special, Saturday Night Music "everyday use" and old songs to dance the night away at -the never heard make would- Disco capable. "The Eve of War" is for me a great example. The only one who is currently playing at the same level as the DB, for me David Guetta.
My top favorites after 1 week listening pleasure: - The Eve of War - A Night Like This - Hey St. Peter - Fly So High
I can highly recommend Vol.10 - even after more than 1 year of the show.
