I have to go with Petrucci just as he is the main guy and has written so many songs, many of which have great lyrics, some of which don't. Myung is really my favourite based mainly on Learning To Live, Trial Of Tears and Lifting Shadows Off A Dream but he only does one song, at most, per album so if we relied on Myung there wouldn't be too many DT albums. I am a fan of La Brie vocally and will always defend him in that regard but not a fan of his lyrics. Also never been a major fan of Kevin Moore's lyrics aside from Space Dye Vest, which I love. Portnoy's lyrics are functional rather than inspired apart from A Change Of Seasons. He does lose major points for Never Enough which is, in my opinion, far and away the worst song DT have ever done. No problem with MP being annoyed with ungrateful fans especially after all he did for them but the song was, as someone else put it, "way too cry-baby". Tool did a song called Hooker With a Penis which was about a similar issue and MJK said it so much better "fuck off and buy our new record" rather than MP's version which was more along the lines of "you're hurting my feelings and if you carry on I may pack it all in". That may well be how Mike felt, and I don't blame him, lots of DT fans are dicks, I just don't want to hear a song about it. Plus it's a terrible song melodically anyway.
