My response:

Do you play in bands?

How many tunes you should know depends on what you do with them.

If you need to memorize tunes to play with certain bands, then that’s probably what you should do. If it’s just for fun on your own, it’s your call. Probably more interesting to learn more tunes in that case.

If you go to jam sessions and they call tunes, then it’s good to know some of them. Etc.
