There is a strong, healthy emphasis on music at my parish. The pastor insists on quality music, the music director is not only very talented as a musician but also a very good teacher. Singing is praying. Our congregation SINGS. And we have a variety of hymnal styles, from traditional Latin to American Gospel. 

That said, it takes more than music to create a strong community. The liturgy is central, and thus most important, and it is essential in creating community. But it does not stand alone.
