Not that I want it to happen but.... if it did, the first thing you need to do is automatically include all of their singles. That is typically what Greatest Hits albums are made of. Second, add at least one new song b/c that seems to be what every artist does on Greatest Hits cds now (how can it be a Greatest hit if it hasn't been released before, are you predicting it will be well received?). That already brings the song count to 18 which is more than is on a typical Incubus CD and does not include any future singles from future albums, so it probably will be a double disc set.
