Last word (for a while) on hardtrance megamixes

Although I've been so excited about them that I've been talking about them way too much, and I still am, it's about time for me to just get to work on making these hardtrance megamixes and stop mentioning every little thing that I've done.  With that, I've now queued up a lot of work for myself, so I should be able to keep quiet now for weeks.  What I've done is the following:

• Finished 6 megamixes, each of 12 tracks each, selected randomly from my hardtrance (and other related genres) "best of" folder, and then opened and manipulated in Audacity into a 12-song "DJ Set" like file, that ranges from about 1h13m to 1h29m. 
• Because the combined file size (192 Kbps mp3s—for the record, even Armin van Buuren says that he can't tell the difference between 192 Kbps and WAV files.  I certainly can't on any system and in any environment that I'm likely to ever play these songs) was about 680 MBs and the standard CD-R is 700 MBs (and because mp3s loaded on CD-Rs are still extremely convenient for me in every respect except when I'm walking around with earbuds on) I made the first megamix CD-R—a hand-drawn stylized picture of a skull in a gas mask and the hand-written label HTM 01-06.  This CD-R has 6 files, but each of the 6 files is made up of 12 songs stuck together in a set-list format, so the total CD-R is 72 songs.
• This is almost exactly 10% of my hardtrance (and related and similar genres) "best of" collection, as it happens.
• I like this format so much, that I decided to continue it.  If I make  10 CD-Rs, with 6 megamixes each, with 72 songs on them each, I'll end up with 720 of my songs done (as an aside, I've just barely inched over 720.  I'll cross what to do with the remainder when I get there.  It will probably be a moot point, because I'll slowly keep getting more files here and there; hopefully by the time I finish 10, I'll have enough to make 11 too and then call this project a day.
• For a variety of reasons, not least of which being the fact that I have poor impulse control, I went ahead and sorted all of the megamixes I need for the next CD-R and even moved copies of the files into appropriate folders, renaming the files so that they appear in the order that they were sorted in.  Ergo, I have 6 more megamixes ready to go right now, only requiring the time to create them.  Which is not inconsiderable; at least an hour to an hour and a half per megamix, and that's if I put relatively little effort into trimming and beat matching, etc.  Realistically, it'll be two or three weeks before I have CD-R HTM 07-12 ready to go.  But, I've got all of the songs and the order in which they'll appear ready to go.
• I also made up a list for HTM 13-18.  I didn't copy the files into folders yet (partly because the thumb drive that I keep them on for ease of moving around between computers is only a 2 GB thumb and they won't all fit anyway.  This is overkill, because I have no need to have this list yet, but I'm so curious about what was coming that I decided to go ahead and do it anyway.  I could have gone even further and made tracklists for all of the rest of the 9 upcoming CD-Rs, but that's a bad idea, because if I do end up slowly adding more tracks and get up to about 11 CD-Rs worth, then I'll want those newer tracks to be more seamlessly blended and sorted in rather than just all loaded up at the end.  
• That said, there are a few irregularities.  I've mentioned before that Immersion's song "My Name Is Acid" is on the first megamix, but was subsequently removed from my list—although maybe it shouldn't have been.  It's the right kind of song, but it's so long and I would sometimes get bored listening to it.  It doesn't actually do a lot.  Anyway, it's a bit cut down and speeded up slightly in my megamix, so it fits fine there, but I don't want it coming up if I'm just playing the original files, I don't think.
• Also, I have the song by System 7 - "Alphawave (Plastikman Remix)" which is so long that it effectively counts as two tracks.  It hasn't yet come up in my sorting (although I've only done about 28-29 or so percent of my tracks, so that's not surprising) but when it does, it'll take two slots and that megamix will only have 11 songs in it.  Anyway, like I said, the count doesn't quite match up to get me to an even number, but that's not going to be an issue for many weeks, if not months, so I'm not going to sweat it too much right now.
• If you look at the lists I just posted, you'll see that I relaxed a few of my rules.  I still try to avoid having the same artist appear twice in the same megamix, although I no longer care if the same song shows up (in different mixes) in back to back sets.  Nor do I worry about the same artist showing up under a different alias.  So my third CD-R will show a number of items that would have been excluded the way I used to do this.
• The combined total of songs sorted and selected so far is 216, which is not inconsiderable, and which represents about... almost 30% of the files to choose from.  I've got a lot of repeats (not real repeats, but different versions of the same song) that popped up randomly, which I wish hadn't, because that means I'll get more repeats further out, making repeats closer to each other than I'd have liked.  But that's the risk you run with random sorting.
