I had heard Katatonia many years ago after I discovered Lacuna Coil around 2001 and was told to check them out. I don't remember what songs I downloaded but I remember not liking any of them because of the weak vocals. Then several years later someone on a Flaw forum mentioned how "mesmerizing" Jonas's vocals were in a new song called "My Twin" and so I (skeptically) gave them another chance and listened to "My Twin" and was completely blown away. That was the quickest turn around I have ever experienced with any band to where I hated them at first and then with just one song, they shot straight up to my "top 10 bands" list. Now after NITND, they are in my top 5 (but only due to their two most recent albums...I am still not completely sold on their older material, save for a handful of songs from VE and LFDGD).
