how many playlists can you have or create

There is no documented limit.

Note that Smart Playlists with Live Updating use extra processing, so if you have more than a few dozen of them you may notice a slowdown.

Some people think they should create a playlist for each album. If by any chance that is the reason you are asking the question, you will find it is much easier to get to an album via the column browser.

Hello, soulman10!

There is no limit, and if there was, I highly doubt you would reach it.
