Now that it's post-graduation, it's safe to share this with the internet! (Due to the fact that it was a grad present for a certain individual who reads this blog.)
I got this cassette-shaped flash drive from Amazon. Unfortunately, it looks like it's unavailable right now. There are other options, but I wanted high quality and a good amount of storage space. I ended up with a pretty varied assortment of songs, hand-drew bubble letters on the cassette label...and ended up with a whole lot of nostalgia!
