I play vocals, sax, wind synth, flute, guitar, bass, keyboard synth, and drums.
I'm in a duo and I make my own backing tracks, so I play at least bass, drums and the comp instruments on each song. Leilani and I save the most fun parts to play live on top of our tracks.
So I save whatever is most fun to play, and I can't say that I hate any of the parts on any of the songs.
The closest thing to dislike is playing "Yakety Sax" which I only play when requested. I've been playing it for way too many years, way too many times, and it is just an exercise in the same fingering with nothing new to explore. So when somebody asks, I smile outside and have a little inner groan inside. Then when the music starts and I put the reed in my mouth and my fingers on the keys I forget about the fact that I'd rather not play this song, I get into it and have a great time playing it in spite of myself.
I'll answer your question in the opposite, depending on the song, my most fun instrument is either sax, vocals, wind synth, or lead guitar.
