Summer 2004: 9.5/10. Good, possibly one of the best summer
Summer 2005: 8.5/10. OK, but not bad. I like all of the summer 05 playlist.
Summer 2006: 8.5/10. Good, but the Storm alert coverage ruined the summer since hurricane coverage isn't the same anymore since this summer. My favorite playlist was July 2006.
Summer 2007: 9/10. A bit better, but hurricane coverages. The music playlist were OK.
Summer 2008: 9.5/10. Tie with 2004, the best summer ever along with 04. However, the hurricane coverages during Aug-Sept kills. 1. They shows that awful blue bar (sometimes red during storm alert). It's the one that shows path, info of the hurricane. This is why I don't do hurricane related on TWC.
Summer 2009: 1/10. Gargabe summer as well as the current year. That awful blue bar is still there as well as the suckish LDA bar. The BBOD and WUWA ruined it. TWC is not the same anymore.
