I have used the Apple Remote app for some time with a iPod Touch. I carry it around the house and, using a Crestron system, distribute music throughout my house and pool area. Just got a iPad 2 and while the software is the same there are a few quirks with the iPad.
One, if the "Album" field is left blank, the Remote app will see the song and indicate its there (in the song count), but upon opening the folder, there appears to be no song there. This is remedied by labeling all Albums for which the field is left blank (I sorted by Sort Album and mass labeled all albums with a blank album field, "Unknown"). This fixed the problem. But still strange.
Again, this problem did not exist with the iPod Touch, but does with the iPad 2.
Secondly (and this one I cannot find the answer), in the iPod Touch, you can choose an artist, then albums and finally press All Songs on the top of the artist/album screen. All Songs arrays every song from that artist's multiple albums in alphabetical order. A big help in looking for a particular song versus searching album by album. I have a 40K song iTunes library, so the alphabetical listing is important. Why/how could All Songs appear on the iPod Touch and not on the iPad 2?
I have uninstalled and reinstalled the software 4 times. No change. If anyone is a heavy user of Remote or has some way to work around the lack of the alphabetical listing, please let me know.
