Tapes might actually be a little cooler than vinyl for packaging options. The smaller size gives a lot of opportunity for creativity in packaging and limited edition add-ons. https://noisey.vice.com/en_us/article/rpb7mr/dig-up-your-moms-walkman-tapes-are-back-in-a-big-way
Yea the tape is definitely a downer, at least it's purple. I never really thought about it before but the reel to reel style cassette (TDK) is limited in time, I think it's 60 minutes or much less. CD's, at 72 minutes, would need a couple of those to fit all of the music so most promo packs wouldn't use those.
