Rediscovering Music And The Downside Of Shuffle

In my quest for writing music that I already own (and thus don't have to pay for), I have been going through my iTunes library song by song to see what I've been overlooking recently.
It's amazing what gems one can forget they own -- the other day I heard a song on the radio that I've always liked and thought to myself, 'I should look that up on iTunes.'
Then I remembered that not only had I looked up that song on iTunes, I had bought it. Four months ago.
It's also unbelievable what sort of trash is unearthed that one used to listen to obsessively. It's painful to listen to some of it at three years' distance.
However, the main problem with this sudden mining for gold is this: I'm discovering rather a lot of gold. And now I want to do choreography to it when I'm supposed to be writing. That or I'm too busy reading every individual line (at least the song title) and trying to decide what old neglected favourite I'd like to listen to next.
I'm rather picky about this. I can't just click 'Shuffle' and let the computer decide what I want to listen to. At first I held this opinion simply because I'm one of those purists who (generally) likes listening to an album in order, or at least certain songs in a specific order (I have dozens of playlists that I made up for this purpose that lasted about a month before they got old and I abandoned them). I also find it jarring to listen to a different artist every four minutes.
However, I also hold this opinion because once I did put my music on shuffle. I was rather enjoying not having to go back to iTunes and pick new music every ten minutes as I typically do.
After a while, it started playing a soft, slow, mild song. That was perfectly fine, but at the end of those sorts of songs, your mind's rather in the mood of a soft, slow, mild song. That and you've turned the speakers louder so you can hear it.
This was the next song.
Perfectly good song; it's been a favourite of mine for years. I just wasn't expecting that sort of intro directly after something so calm and soothing.
I wouldn't say I 'swore off' shuffling my music after that, but it was a definite contributing factor to my personal dislike of the practice. I suppose, though, if I get quite pressed for time on the novel I could shuffle my music to save time (although I doubt it'll be needed). I just hope the computer will consider my tender heart if/when I give it free rein.
But knowing this computer, it probably won't.
