Top items I use for planning various events like weddings, birthdays, summits. They are helpful form me and I hope someone will try at least one of them. Good luck!
1
Music
For music, I always go with spotifypremium
And why I bolded premium? Advertising, you do not want ads to interrupt some nice songs.
2
Planning tool
Best planning tool for me: trello
Easy to use. You can create your own lists, cards, add labels, attach people.
Just give it a try, you will not be disappointed.
3
Guest cards tool
If you have a lot of guests, which I usually do, I often place table cards for them. I recommend trying this: nameacard
If there aren't design you like, you can always contact support and they will gladly help you with your design.

Ideas
Missing ideas? Check Pinterest
In Pinterest you can always find something interesting. I often spend hours just sitting in couch and scrolling pinterest.

Facebook groups
Need to buy something? I recommend using Facebook groups which sells funny/entertaining items. You get cheap and good quality items.
