Instead of concatenating a string, just make your key an array of the
values.
hash = {}
key = [date, album_id]
hash[key] = value
However, hashes are not sorted in Ruby 1.8. Rails 2.x has an OrderedHash
that maintains the keys' nsertion order, but it's not efficient for
lookup by key. If you only plan to use the hash for iteration, that's
probably OK (but then why use a hash?).
