You kids these days have it too easy -- I used to type them in by hand, make the graphics, etc. RSS feeds make you rely on another website, which can slow things down quite a bit, and are not totally reliable.
As Jeff mentioned earlier -- people at weddings aren't looking to hear stuff that hasn't charted yet. I've found they tend to like the music they grew up with, when they first met, etc. I generally do crowds over 35, so they really don't care about new, breaking stuff. Just my humble opinion.
BTW, the errors usually show up early in the morning -- don't get any errors on any of the other sites I frequent. Perhaps the server dude is doing backups or something... Don't know...
