what mastering gives you normaly is a track that sounds overcompressed, distorted and just fucking loud, gives u headache and tired ears and shit-sound just so u can hear the track on shit TVs and car-stereos. stay away at all costs.

Thanks for the advice guys.

To clarify. What I mean by "flat" is that it does not sound like its full range. For example the lows don't seem to get as low as other songs do.

When I play this song on my better setup, the LFO is not making as much sound as I'd like it to be.

I tried making the lows higher on the EQ but it still does not go to the sub whereas other MP3s do have that full sound.

The lows on the kick or the lows on the bass?

As I said, for most of the song I couldn't hear a bassline. I thought potentially there was a subbass down there, but it was too low (frequency-wise, not volume-wise) for my internet computer's speakers to pick up.

If the kick doesn't have enough lows, either find another kick sample or try layering with a sub kick. It does sound odd though. Many times kicks and basses have a bit too much sub content and have to be filtered away a bit.
