Dont know Pandora: yamaha do a very neat 4-track with all the editing facilities for the sort of thing you're talking about. (I know nothing about techicalities, but I have recorded three CD's using Yamahas, 4 or 8 tracks home studio things, and I found them just fine. But I'm sure there lots of others, I hope people wwith more experience will come by and give us the benefit of what they know. I'd be very interested with more info.
