Depends. A lot of my material is pre-written, as in, I write reviews in advance and then later on decide when to actually post them. I also have a list of "sections", which I add to and check as I go along, so that if I haven't done a particular section recently I might think about going back to it, as in today's "NO! It can't end like this!" slot. I'm also working on only the second "Crashing solo" feature, the last of which was sometime last year.
Often I just like to review albums I love, but sometimes ones I hate; then again it can be a case of well I did a prog album yesterday, a metal one the day before that, hmm... how about Barry Manilow?

Or something similar; a chance to keep everything as varied and eclectic as possible. I prefer if possible not to review albums from the same genre too often together --- unless I'm doing a series or feature --- and even then, I try to ensure the journal isn't just jammed with album reviews, slotting in other sections like "What's in a name?", "More than words" and so on.
There's no actual set plan: I actually have too much music to ever be able to adequately review all my albums. In general I try if I've reviewed an album by one band to not do another of theirs for a while, perhaps months. This great restraint is shown in my only reviewing two Marillion albums in all my time here, even though they're my favourite band. Excuse me, three: I forgot "Somewhere else", which was reviewed in the "Last Chance Saloon" --- must do that again soon, but I digress. If I only concentrated on the albums I love then this could become quite a boring and predictable journal, but really, no-one knows what I'm going to come up with next, least of all me. I mean, who else would think of reviewing Black Sabbath and then Pixie Lott? Or Holst's "The Planets"? Or Vangelis? I like to surprise my readers, throw them a little off-guard. Lisnaholic said that on his first visit here last week he was surprised not to find just prog albums. That's the kind of reaction I'm going for. It's like, wow, you're a prog head but you listen to Robbie Williams/Steve Earle/Motorhead? Keep em guessing, say I!
But yeah, that's it. Sometimes I'll have an idea what I'm going to review, sometimes it's taken from something I've already written, perhaps weeks or months ago, and sometimes it's almost stick a pin in the map and see where we end up, as it were. Much more fun that way. But hey, that's my style, might not suit everyone.
