Hotaka isn't their newest tune man, it was released in 2002. And if you don't like the original (it isn't my favourite either), check out the Thomas P. Heckmann Remix, it rocks! That is if you like techno though.
As for the original question, yes Juno like all others have made bad tracks, that goes without saying. When you make that much music not all can be brilliant. They certainly have a pretty big majority of quality though, and right now I can't remember the title of any straight out bad tracks, even though I'm sure they exist.
