One of the biggest helps is realizing you don't match the booom boom boom boom sound.

You match the

boom "CHUNkT" boom "Chunkt" sound.

Listen for the "Highs"

Its a little tick in the beat. Most styles have it.
Breaks, Drum and bass, trance, and especailly house have hig hats to mix on.
Just keep practicing. Also a GOOD monitor speaker, mixer, phones and needles help sharpen the sound so you can align the bars perfectly.

I like digital mixers. Don't fo for power with the monitor speaker go for clarity. I'm not too technical hope this helps.
