I forgot a important thing I learned on here.
I’m cycling through my recent threads made to find out this post that was teaching me lots in my mixes.
As I can recall it said mix track b into track a after 16 bars or something like that.
So i’m not sure if its 16 bars or 8 bars or 32 bars. Anyone clear this up for me? 
oh man…sorry to say this, but you really need to spend more time practicing and less time asking these questions here. you don’t seem to have learned anything since you asked this a month or more ago when you had no clue on how to mix 2 songs together at all. this is really, really basic stuff here.
no one can give you an “always mix the track in at 32 beats” because it’s not a black and white rule. not all songs are structured the same and it depends on the genre (which for you i think is trancey sounds…so probably a longer transition period). mix it in where it sounds good (use your ears) and look at your visual waveforms (use your eyes) for clues (i recall that you are using traktor). practice, practice, practice, practice, practice…did i say that enough times? practice…
Don’t you have that moment during track a that you know you must start track B. It’s like a uncontrollable impulse, when you feel that just start it.
I usually count in 8 bars. But there could be single or multiple series of 8 bars.
It’s feeling the track that counts. If the track tells you you can start mixing now, go for it.
Might not work for track c or d or…
Some tracks you can press start at the same time and they mix absolutely perfect. What an odd way to look at music and mixing, so robotic!
Don’t worry about mixing at the 8 or 16, mix when the next track sounds perfect with the previous. Drop them at the same time, drop one 8 bars in, drop it after the buildup, whenever. The only way you will know when to play the next track is by practice.
Edm follows roughly the same pattern, but every song is different. Unless you give us your track list, we can’t tell you when to mix in, but don’t give us your track list, its lazy.
Spend more time on the decks, and less writing long threads about how to mix. Check out ellaskins or dj angelo on youtubes.
Always start the next track with exactly 1:30 remaining. Can’t go wrong! 
Does anybody else wonder if Hola Amigos is the worlds most devious troll?
He sure does have an awful lot of posts…
Pretty sure he trolled me just now.
lol it was me that helped you… i think the post was some ridiculous troll thread and you were flamed alot lol but i still helped well use the search function 
no more trolling homie
i don´t want to sound rude or anything, but imho you should start using your brain. if you would have done this before, you wouldn´t ask this question. you have defo gained enough experience while the time being here to realize by yourself, that there is no rule or law when it comes down to mixing. math can´t help you mastering it. your own experience only can do this. 8/16/32 bars…won´t help you much in the end to become good. it´s your ears and your knowledge of your own tracks. practice every day, get to know your tunes, don´t worry about the theory. if the transition doesn´t sound good, try another tune and so on.
just my 2 cents…
I do it actually quite the same exept that instead for starting i realease it from it’s loop
ahhh… he switched avatar 
yeah, but the number 1 troll spot goes to another dj i’ve know for 10+ years. he’s got that super esoteric, long troll game that he uses on 4 people. it’s pretty epic.
LOL, that’s awesome!!
For best results, I do 8 bars. By the time I hit 9th bar I’m too fucking wasted to mix.
Alright i’ll use my ears more. But i stop counting in my brain and let the software count. Then try and transition and it sucks ass. lol
yup, to this day i still can’t quite tell if he’s trolling us or if he’s just extremely delusional. if he is a troll it’s like some andy kaufman level brilliance on the most micro level possible…that’s he’s kept up for y e a r s. if he’s not trolling, it’s just sad really…
lol
just keep at it and practice as much as you can. like others have said, you will start to get to a point where you can just FEEL where most songs want to be mixed. for some people this can take time for other’s it comes easier. a fair amount of house/trance music (@ ~125 bpms) you can start a mix-in when there is around a minute of music remaining in the first track (which should be 32 bars at that tempo). this isn’t a static rule but start there and see how it works, adjust as needed, and really listen to your tracks and understand the points that make sense to mix. then feel it!
