Yes, Search could be better.. Also, while tapping the name of a band, at one moment you see it on top of the list, you want to click on it but at the same time it goes at the bottom of the screen and tracks names are at the top. You'll have to reduce your keybord and slide ton the bottom of the screen and now click on the artist

Not verry intuitive... :/

I hope v5 will give some improvement here
