just youtube search non copyright intro / funny songs / goofy songs / happy songs etc
there is a ton of them!! but be warned, if you use non copyright and an artist gets picked up by a label, it will all of the sudden get copy righted. chances are super low..i usually try to go with ones that have less views and less popular.
You're bumping a thread from 2019 by which was last replies to in Feb of 2019 and the OP hasn't logged on since April 2020. As a reminder, if you hover your mouse over their names, you can see when they last replied. It's not a good idea to reply to dead threads as it makes people think they are still alive. especially when the OP hasn't logged on in months or the thread hasn't moved in months.
