Hi patricia, I've put on 24 at one time up to now on my daughter's site & have had more but that's only whilst I've been sorting the music out. However they have all played when all 24 have been on so the answer to your ? is, I think, as many as you want...But, please be aware the music player is slow to load and/or you may experience difficulties with too many~think the best way round it is to make a list of all the songs you want, then split them into say 4 shorter lists & maybe try rotating each list on a weekly basis. Hope that helps & makes sense?
Love & blessings,
