I recently bought Five Years (and Who Can I Be Now) from eBay. Since I live in New Zealand, I went for the cheapest shipping, which was China. I've already bought many of the CDs individual before (sometimes multiple times), so I have multiple copies on my hard drive. I also am comparing against Spotify. I find the CDs in [my copy of] Five Years to be very loud compared to the individual CDs. At first, I thought that maybe I got ripped off, but then I compared some of the tracks against the Five Years tracks on Spotify and it sounds like my levels are similar to Spotify. But what is so strange is that the "remastered" Ziggy tracks sound so much louder than the "2003 mix" tracks. For instance, "Moonage Daydream" is REALLY LOUD in Spotify and on the first Ziggy disc, but on the 2003 remix is it much softer? So can someone please clarify: are the Five Years CDs mastered really loudly, and is the first Ziggy CD significantly louder than the 2003 remix CD?
