The first all-digital MeFi Music Mixtape Swap signups are open until April 14, so if you're into it, share the love! If you're in need of some inspiration, you might check out some of the more than 50,000 78rpm record sides available from the Boston Public Library now on the Internet Archive. But if that seems a smidge overwhelming, maybe just queue up the one song that apparently nearly every other human on the planet has listened to? That's a lot. Too much? How about just that one special part of that one song that you love so much, but, like, it just keeps going?
