I have just uploaded a new version of the band name generator.
This has probably around 10× the number of words as the first version. Due to the size of word list, rather than doing everything using javascript in the browser, this new version does all the clever stuff on the server in PHP. This means it is less likely to crash the browser. There is still some work to do before it is officially launched— notably I need to go through the word lists and remove a lot of the crappy/obscure/archaic words.
Currently I'd say the app is a fair bit less useful than the previous version due to there currently being a lot of crappy words in the source lists, but once I have edited the lists down, it should improve.
