I know CDCopy used to have the feature of remembering the CD's ID and then batching the CDDB query for multiple CDs. This required you to feed it all the CDs you were going to rip before you logged on, then do the update online, and then you could rip them offline. The feeding is pretty much just inserting the CD, waiting for it to recognise the new CD, and then ejecting it, from memory.
I think Exact Audio Copy does this but I'm not sure. I'm spoilt now I have cable.
Save the whales. Feed the hungry. Free the mallocs.
