I tried Collectorz on my Android tablet and didn't much care for it. Importantly for me there is no easy way that I found to include all the sidemen, much less indicate what tracks they play on. It is also not very adaptable in that you are pretty much stuck with the displays that were programmed in. It does, on the plus side, make it easy to add albums as it has a large database of its own that it draws from.

And as for Norton, is there any program it doesn't make run worse? I haven't used it for years once I found Avast.
