Reply to Chart music transitions?

Hi everybody,

I used to mix a lot of house and minimal back in the 90s but I'm not a professional DJ. Most of the time I made mixtapes for me and my friends, so I have at least a basic knowledge.

A while ago I started to digitize my records and using Traktor now for my mixes. A friend of mine is having a big birthday party soon and he was asking me if I would like to take care of the music. I feel very confident mixing house and techno tracks, but since I'll have to play a lot of (dance-)chart music too I could need some tips how to transition between pop songs. I guess it would be fine with no transitioning at all (noone would probably care) but I don't want to wait always till the end of a song and then just start the next one.

My problem is that a lot of these songs don't have a long intro or outro and/or start immediately with vocals. Any tricks how to do that?

And sorry for my english

Thanks a lot
