Just everything really, from the guitar I play guitar/bass guitar, to how I listen to music etc.
In general I listen to less metal compared to years ago.
More indie, post-hardcore (no, not that metalcore stuff people call post hardcore now, I mean ACTUAL post hardcore without the metalcore elements like Thrice, At the Drive In, Refused etc), more alternative rock, more hip hop and more classical music.
I was going through a big 'prog' phase for a while, but came to really appreciate simpler song structures more again.
When I do listen to metal, I listen to far less of the 'traditional' styles, and more post metal (Isis, Pelican, Cult of Luna etc), and less technical, less complex alternative metal stuff like Chevelle, Splat88's band March Hare etc.
The Sneap forum really taught me that less is ALWAYS more when it comes to arrangement.
Get rid of those bazillion layers of keyboards and guitars in the music, just use the bare minimum you need to get the musical point across and bam, suddenly everything now has room to breathe and sound huge rather than a bazillion things fighting for sonic space and consequently sounding so tiny just to fit in there.
Also has the side benefit of making the song writing sound much more focused and in control too.
Playing more bass guitar, as well as the Sneap forum, really helped me to recognize the importance of bass guitar in heavy music.
Again, less is often more when it comes to bass guitar. Playing too much often leaves things sounding muddy and overblown.
