The sounds are good, but I assume you eventually tightened up the timing on the acoustic guitar track Come closer to me? I do agree, the more you work with biab real tracks, the more you figure out ways of making the best use of them. It's difficult to get them to completely conform at times. Sometimes it's actually helpful to let them lead the way- letting the ideas of those musicians and what they played be the part, as opposed to reworking a part using them. Having used real tracks for a while now, there is no doubt they can be a viable part of any arrangement, at any level. But it does help to have good editing chops, be able to add real instruments, and have good drum samples handy to help the drums conform more to how you need them to be in various spots- cymbal crashes and hits being a big one. If you have all that, and a good song of course, there's no reason not to use biab if you choose to.

I assume you didn't use the audiophile version either, which is 24 bit wav files?
