Take some time to think about your past. Are there any bands that you loved/liked in your younger years but as you've grown up and listened to other stuff you've slowly forgotten the bands you loved/liked or tracks.
Small list of some bands and their tracks I remembered recently.
Soil - Halo
Devil Driver - clouds over California
Fear Factory - Linchpin
Engel - casket closing
I don't have any favorite tracks...more or less bands....
