Hi guys. Sorry it's been a while, but I have finally converted all of your songs to mp3s and would like to have them to you by Friday of this week. I've been putting this off for a while, admittedly, and I'm sorry I wasn't more on top of things with your requests. I will keep you posted on the status of them and you will get your songs, I promise.
As for a few lingering questions with regards to the BRSTM program that's in the OP: It's outdated, it's not going to be updated, and I've never used it myself because I have a much different method for making BRSTMs. I aim to have a guided tutorial with pics/possibly a video by the end of the summer, and hopefully some of you can follow it decently and learn to make seamless BRSTMs yourselves. With custom music now a thing in the Wii U version, hopefully even more people can be exposed to custom music and the joy of hearing your own songs play while you're Smashing with friends.
