Using the Xbox Music app on Xbox 360, search for an album that has a lot of songs.
Take Made in California by the Beach Boys. Or Metropolitan Opera's "Wagner: Der Ring Des Nibelungen."
Both have well over 100 tracks. But search for them on the Xbox app and they only display the first 25 tracks. I searched for lots of different large albums and all of them showed the same behavior.
Someone reported this problem in another thread back in September, and we're still waiting for a resolution.
