Boom, no time to mess around, here we go:

Songs with ‘fat bass’ often actually have way more mid range than bass. If it sounds big and ‘buzzy’, it’s all about the mid-range. It's all about the mid-range in general - bass and treble are for kids.
High pass filter everything that doesn’t need to have any lows in it. Just do it. I bet it sounds better.
Don’t forget to low pass tracks to cut off unneeded top end sizzle. Cutting top end off (drum) room mics is often pretty sexy.
Turn everything down. In the digital world, red is (almost always) just bad. Make sure all of your tracks are recorded @ 24-bit and with a ton of headroom. All channels shouldn’t be clipping when faders are at 0, especially the master fader. Get your tracks PEAKING at -6 to -8dBFS and everything will sound grand.
Work hard to learn to interpret what people REALLY mean. Sometimes ‘this needs more bass’ actually means ‘there’s too much treble’. ‘Turn down the harsh top end’ can mean the 3-4KHz area, not 10KHz+
Chorus (the effect) isn’t just for Spandau Ballet lovers (like me). Use them with a low LFO rate to get super wide stereo sounds. I recommend Soundtoys' Little MicroShift, an Eventide H3000, a Yamaha SPX90, or simply the stock Logic chorus plugin (Super Wide preset). I'm sure whatever you have in your DAW will work fine. Mono -> Stereo, slow LFO speed, bosh, sorted.

There. Enjoy.
