I like most of the tunes I play, and with the ones that are played a lot and/or start to get tiring to play, I try to find something in the music that I can add without affecting it's overall authenticity too much, yet give me a bit of inner satisfaction.
There are tunes I generally "have to" play...Last Date (Floyd Cramer), A Whiter Shade of Pale, Music Box Dancer (Frank Mills) to name a few...fortunately I like these tunes a lot...for a change I may play Whiter Shade using an orchestral string arrangement as the tune borders on the classical...for Music Box Dancer, I use acoustic guitar instead of piano. For Last Date I sub in a pedal steel for piano.
Playing all instrumentals does not give me the advantage of different lyrics for each verse/chorus, so I have to work a little harder on the arrangements to make them more interesting, for both me and the listener.
Thankfully, I find it a lot of fun.
