Having only ever heard the song once and it instantly put me off DT many years ago and ive never listened since.
Oh dear, sorry to hear that! Good clip though, heh, sounds about right. Might I recommend some other DT albums, as you have only heard one of their least popular ones?
Awake
Scenes From A Memory
6 Degrees of Inner Turbulence
Their last album was actually not too bad, they went on a downward slope after 6 degrees, as far as I'm concerned. They bottomed out with Octavarium and Systematic Chaos, but I think they brought it back to form with Black Clouds and Silver Linings. Some others you may wish to avoid are Falling Into Infinity and When Dream And Day Unite, which are both pretty weak save a few choice songs on ...Infinity.
