Another site that I have found very useful is http://www.arabicmusictranslation.com/, which has lyrics to songs in Arabic, with translations to English.

Songs include different types of phrases, some that are used in day-to-day speech. Many of the songs are also sung in a dialect (often Egyptian colloquial). For example, the phrase ايه يعني (aaya ya’ni) which translates as “so what?” in English.

The person behind the Arabic lyrics site recently started a second web site, http://egyptianarabiccourse.blogspot.com/ where he focuses on the Egyptian colloquial dialect with examples from song and more detailed explanations of the lyrics. This looks very useful, since colloquial is the day-to-day spoken language and is essential to learn these types of phrases.
