I don't know, I have friends who listen to some music I like, but lots of music I don't. If it's trying to recommend by that, it's going to miss a lot. And even within my own listening, there's plenty of bands where I like one song, but hate the rest of the album. There's bands where I'm massive fans of certain albums, but only like one song on others. Music's a weird one. And taste changes. Last night I was listening to Jazz, I usually hate Jazz. Should it start recommending that to me now? I can imagine what works brilliantly for some people will be abysmal for others (but I guess a decently advanced ML system should detect that and try different approaches for different people).
