Shuffle songs by artist on iPad iOS 5

After my iPad 2 was updated to iOS 5, I got an issue with music app. When I chose my desired Artist in iPod app and wanted to listen to all the songs in shuffle by one Artist in multiple Albums, I noted there wasn't a "Shuffle All" option. If I shuffled one song, it only shuffled within one Album.How to fix the issue on iPad* There is a search bar in the bottom right corner of the music app.
