I am considering upgrading my JB7 to a B2. I have backed up my music (consisting of a mix of CDs and LPs) onto a USB. If I transfer the music from that USB to a new Brennan B2, will they appear on the new B2 Brennan in the same order as on my JB7 (the order in which the music was loaded in the first place) or will the new B2 Brennan re-index the music itself?
