I'm not intentionally picking on any specific person with this, but I think it's extremely humorous how everyone says things like:
The Grammys have gone seriously downhill in the past 20 years, and most people who listen to anything other than radio-friendly schlock know that, thus we tend to rag on The Grammys, those who nominate and vote, and the whole process.
This does not change the fact that it will still bring some recognition to Dream Theater, which is a good thing, and it was quite a surprise that they would actually be nominated.
Also, note that most comments in this thread, when mentioning The Grammys, still consider them pretty much a joke and a popularity contest, so that hasn't really changed.
