As I said in a previous thread, I can see some value to using genres, like if your brain is so puny and undeveloped that you can only think of what you want to hear in clouded generalities. But if You're Smarter Than A 5th Grader, they're probably more likely to cause you pain, as Zod is now discovering. Grouping things alphabetically could solve the too-much-scrolling problem with a lot less mental anguish.
Listening to individual songs on random is for flaming poseurs, except when you're drunkenly playing "Who Can Name The Song The Fastest" with your friends.
Using "shuffle by album" to get suggestions for the next album to listen to is an approved usage, however.
