I agree with Jim Kroezen.
http://techno.org/electronic-music-guide/ this site has also helped me a lot in explaining where certain genres originated from. It might not be totally up to date, but still, it’s pretty useful.

If you want to dig deeper into music history, check for full documentaries on youtube on the genres you are interested in.
Like, the ones in which good-old dj’s explain about the start of their movement..cool stuff.
In case you like dubstep, go check this one: [media=youtube]WORom53h-Co[/media]

Musicwise there’s just the ~500 songs that everybody knows and wants to hear. Think in terms of soul, funk, disco (stuff for dancing), classic rock (stuff to sing along to), some hits everybody knows as mentioned before.
Then at the party try to get a feel of the audience and see how far you can integrate your own style in it!
As people drink more they might be more open to certain kinds of music, but keep some recognizable elements in in 🙂

I also use that site mentioned above.
Or try to google indeed…most classics have an acapella version somewhere on the outer borders of the interwebz

Forgot to mention another tip..

You probably already know it because you combine electro house and moombahton but ok.
Try slowing down some ‘Dirty Dutch’ electro tracks (by Afrojack or Chuckie for instance) to 110 bpm and there you go!
It’s how moombahton started, after all 🙂

#mce_temp_url# Here’s another one, Shock One – Polygon (Dirtyphonics Remix)
Goes from 175 to around 132 bpm.

Or just mix some different styles, sometimes hiphop goes well together with dnb. Try playing Missy Elliot – Get Ur Freak On to a drum & bass track, loop the sitar part (or whatever instrument that is in the intro..?). Move on from there to moombahton or something.

Plus, if you search online really well you might find some transition packs online, I once stumbled upon one which has come in handy many times already 🙂
Hopes this helps!
