DWOT is a great album and is highly regarded among SX albums, but I just want to say I don't think the percentage would be anywhere near that high - few bands would have one album command 90% when it comes to people's favourites. In fact I'd say I see V considered their best more often than DWOT - and that doesn't even include the many people who favour the newer albums over the old ones.
Does anyone else find that they very rarely discover a band that they really like? I've tried out a lot of the bands being recommended here and I like quite a few of them but I just find that even though I might try something out and think it sounds quite good, it's very rare that I find something I actually want to come back to or keep listening to over and over like I do with my current or permanent favourites. I might listen to something and think it sounds good but never come back to it, or listen to an album a few times after I get it but then rarely ever go back to it later. Seventh Wonder is one of the last bands I actually discovered that really made it into my permanent rotation as a band I frequently go back and listen to, and it's been two years since I first heard them.
