to the djs out there

Probably an interesting read. Advanced Vinyl Handling, DJ Basics And the main hyperreal DJ page.

I would say making the "list" first and then try to fit it together might not be the way to do it, at least if you're a newbie.

Some tracks just won't fit together, no matter how hard you try.
There are a lot of parameters to consider: BPM, key, rhythm, style of the track, vocals, intro/outro style/length and so on.
Usually mixing two similar tracks together is easier but sometimes the contrast between two very different tracks makes it more interesting.
Skilled DJ's seem to be able to mix whatever together perfectly on the fly (while smoking/drinking + talking to their friends/some girls) but I guess they just have a lot more knowledge of their records and what's possible and can quickly decide if a certain transition is worth trying or not.

When you aren't that skilled, start with a "list" of records but count on some experimenting with track order (perhaps excluding some "impossible" tracks along the way) before you end up with a decent mix.
My experience is that it won't be as you planned but hopefully it will sound OK.

I'm talking about beatmixing here, just playing records (quick fade in/out) might not require that much work but can sound good too (and still require some skills, making it look/sound easy is sometimes harder than you think)

yes, start with beat mixing but in the end you can't learn to mix from books or what others tell you, you have to learn it yourself because you have to HEAR it. I'm sure you'll learn to mix electro, it's not thàt difficult.
