My advice would be to most definitely learn to beat match with house before you move on to any sort of beat that is "broken". I would highly suggest a deep house track that has a very prominent 4/4 kick/bass drum. Learn to just match the beats before you go on to try to blend using EQ and such.
Here's my process for if you're trying to learn beat matching:
- Get TWO copies of the same song that you know very well.
- Turn on your system and make sure both faders are at a decent level with the crossfader in the center.
- DO NOT PUT YOUR HEADPHONES ON, the idea is that you will first manage to hear both tracks at the same time over the system and manage to match them this way. You've got two copies of the same song so they are going to have the same tempo and be structured identically. Once you master this aspect try with only one copy playing over the speakers and beat mixing the other one in using your headphones this time.
- Practice makes perfect. Try beat-matching the same record in different places, to make an "extended mix version". Do this until you've got the basic mechanics of the process down.
- Recording is an optional but useful step. It not only helps you to hear your progress but also gives you a reference point to your growth from square one. (Cassette tapes are ideal for this, especially if you are working with vinyl. Analog to Analog sounds great!)
- Try mixing with different songs now that are very similar and aren't extremely varying to much in the way of tempo. This will give you a better feel for the concept.
- Lastly is to experiment, if you are ready to see how good you're skills are try to mix cross genre's, such as mixing house into breaks. Once you've got the basics down you're good to go on just about any style, but I would certainly layoff any advanced mixing technique such as EQ-blending and FX mixing until you get comfortable with basic mixing. Remember: the simple crossfade and the cut are your friends.
Also, I'd like to advise that just because two tracks are going at the same speed and are from the same style of music doesn't mean they are going to sit nicely together, the musical elements that make up a track are important too. Listening to mixes by other DJs (both Pro and otherwise) from all sorts of genres helps a great deal too, by trying to understand what they are doing during the mix, their song selection, and the quality of their mixing you will learn a great deal of how to master this ridiculously fun art form.
