Do you or have you ever found yourself recycling ideas from your older songs in your current or newer ones ? Do you ever find that you repeat yourself or do you always strive to be completely original with each new song ?
I like reusing thematic passages to create a sense of musical connection between two pieces of music, and if I'm feeling really clever, I'll reuse them in ways that subtly reflect connections between the lyrics themselves.
For example, the (Latin) Gloria contains the phrase "Qui sedes ad déxteram Patris, miserére nobis" (who is seated at the right hand of the father, have mercy on us), and the Credo (Apostles' Creed) contains a similar line, "Sedet ad déxteram Patris omnipotentis" (sits at the right hand of the father almighty). Despite my settings of those two Mass parts being in entirely different musical styles, with different instrumentation, I used the same basic musical phrase in the Credo that I used in the Gloria. It sounds different, but similar enough to make you think, "Aha."
And every now and then, I'll gratuitously slip famous musical works into psalm settings—ideally in ways that call to mind other works of music that are thematically related. For example, in my psalm setting for the Feast of the Baptism of the Lord (the last day of the Christmas season), the alto, tenor, and bass parts interact in subtle ways so that when you hear all the parts sung together, you can distinctly make out the second phrase from Gesù Bambino, as the choir sings, "The Lord will bless his people, his people with peace," alluding to Jesus as the Lord's blessing of peace upon his people.
Or in my Lamb of God, the tenor vocal line and chord changes for the third "Lamb of God" are ripped straight out of ELLACOMBE (e.g. Hail To The Lord's Annointed; Hosanna, Loud Hosanna; etc.) just to distinguish it clearly from the first two, and again, subconsciously making people think of those other pieces of music, both of which are (at some level) about the same subject.
I realize all of these things are subtle enough that probably no one will notice them, much less recognize what I'm doing or why, but the musical world has a long tradition of such cross-references that dates back to at least the classical period, if not earlier, so I'm just trying to continue that tradition in new works.
