A year! That makes you a new boy! It happens all the time. Record labels come and go, record labels decide to pull artists from Emusic. At some stage they may or may not be back. I've been a subscriber for about 8 or 9 years and you just get used to it. I've known albums to disappear within a week of appearing. If it's important you get it then download it as soon as you see it. I always make sure that I have at least 30 downloads available in case something new I want appears near the monthly refresh day. Of course, in the old days, when you could download as much as you liked, it wasn't a problem.

As JohnW says, content comes and goes regularly, so grab the important stuff while you can. I've even had things disappear from my download history list, which seems a bit 1984 to me as it looks like they're pretending it never was available! It is also a bit disconcerting as it means I wouldn't be able to download those again if I needed to, despite having paid for them, but I suppose that's why we back things up.

On a similar note, it regularly makes me laugh how angry some people get on there when something isn't available (i.e. a single, but not an album) or is only available in the US but not the UK. Comments like "Sort it OUT emusic!" are common and just sound like petulant teenagers stomping their feet and shouting "It's not fair!" They genuinely seem to believe that it is emusic mailiciously withholding things rather than a decision made by record labels (or the fact that bands are on different labels in different countries).
