Does anyone know of any "Must have" song lists out there on the web? I would like to hear some new or different music sometimes and I get bored with the same old stuff.

I was browsing around and there is a ton of junk on the search engines. I was kind of looking something that, is perhaps, sorted by year or genre.

Has there even been a thread posted on this BBS with a list of "must have" songs for people to add to their collections?
