Dust indeed.
Well to be fair it only takes a few weeks of non-use around here for something to collect a thin layer of dust, but I hadn't listened to Definitely Maybe in at least 6 months. I also noted that this CD is in pretty bad shape, but after as many times as it's been listened too over the last 14 years, I'm a little surprised it even plays. I really need to replace this CD, What's The Story (Morning Glory), Which is in worse shape, and Be Here Now, which meet with a rather bad accident that left it unplayable.
