Have you not got a fantasy set?
I've had one for a few years now. I add to it sometimes and other times I drop numbers from the shortlist but I have a core of popular songs that I like. I put the tunes onto random play with the bass turned down and play through a few songs at a time without pause. It sharpens me up on the intros doing so. I do need to work with live musicians though. Recordings are inflexible carbon-copy-every-time propositions.
The repetitive aspect can hit you at some point and you might wish you never had to play some of them again but then isn't that what happens to working musicians anyway? After a bit, that goes away and you can often find yourself rediscovering an old favourite from a completely different point of view.
I have about forty songs (covers) in my set. I'm happy with that number for my own practice but it leaves room to learn new songs in order to satisfy a role in another band down the line. Bear in mind that I have not been in a band since 1987.
