This is my personal list of sites with mp3 and other recordings of nusach and Jewish liturgy. I collected these links because I am deeply interested in the music of Jewish liturgy, and I want to learn every melody there is for everything. I am not likely to ever reach this impossible goal, but this list is my attempt at it, at least!
These resources are arranged by an algorithm that considers how extensive a resource the resource is in each area. This consideration is subjective, but if you are looking for a particular High Holiday tune, you are more likely to find it toward the top of the High Holiday page than the bottom. Resources in gray boxes contain significant non-Ashkenazi nusach, in some cases alongside Ashkenazi nusach and in other cases to its exclusion.
Keep posted, since I add new resources to this list from time to time. I am also working on a larger project, NusachDB, to collect the melodies themselves. If you know of any useful sites not on this list, or notice a miscategorization, please let me know at email@example.com. Notable missing (or not well-covered) recordings include the Saturday night portions of Maariv, Kiddush Levanah, the Hoshanot of Sukkot, the Hakafot and Chatan Torah passages of Simchat Torah, the Al Hanisim paragraph in the Amidah and Birkat Hamazon of Chanukah, Purim, and Yom Haatzmaut (in the Conservative tradition, anyway), the Haggadah chanting of the Magid and others, and, of course, any less famous melodies for well-covered services like Kabbalat Shabbat and Hallel. If you know of any sites with these, please send them along, or hey, record them yourself if you'd like!
Click "Catalogued recordings" to see which recordings or sheet music in a particular site have been added to NusachDB. For the foreseeable future, these do not represent the totality of recordings for most sites, but the lists will get more complete with time.
Please enjoy this list and may it increase your learning.

2. Virtual Cantor
Great site with mp3's of nearly everything. This should always be the first stop. His nusach can be unique, at times, and he has great melodies that are hard to find elsewhere.
3. Het Levisson Instituut
This is a big collection of very musical Dutch Jewish nusach, including sheet music in many cases. It covers many services, including weekday, Shabbat, chag, and High Holidays, with multiple versions at times. This is a very extensive resource. The nusach is in large part compatible with the common Eastern European nusach, and a large number of lectures are provided on the subject as well. The sheet music uses Dutch transliteration, however, so it will look funny to English speakers!
In Italian. Huge archive of Italian recordings, including Italian laining, Italian nusach, and classes. There's a lot more there than I've been able to properly categorize, especially without an Italian siddur, so the notes below are (and will probably always be) incomplete.
5. Seder Chazzanut Amsterdam
Dutch Sephardic nusach, in old recordings, for scattered parts of weekdays, Shabbat, holidays, etc. Most pages are in Dutch, but Google translates them well enough.
6. Dorshei Tzedek
Various recordings from a Reconstructionist congregation. Note that the Reconstructionist text can vary from the original at times. Includes Torah blessings (with text) elsewhere on the site, and includes trope as well.
Note: includes what they call a Shivah service, which is a weekday maariv
7. Temple Emanuel (Newton, MA)
Very well-chanted recordings of the weekday maariv and shacharit, Shabbat morning, and Shabbat mincha services. Includes V'hi Noam, the additions for Saturday night! There are also Pesach and High Holiday recordings under "Music". Temple Emanuel used to have an old site with Shabbat morning recordings as well. Those recordings are still available there, though the rest of the site no longer exists.
Note: includes a maariv service for a house of mourning
