My one complaint is that the music library paradigm in Clementine doesn't feel cohesive, so unfortunately it is relegated to streaming music for me. I really don't like that I can't play music directly from the library and have to make a playlist: it feels very cluttering. This is even (or especially) true for streaming stations, in order to try a new one out it must be added to a playlist. If I could change one thing about Clementine, it would be to allow playing of music directly from the library.
