I set up this ‘Hallelujah’ playlist earlier this year to illustrate the difference between ISRC and ISWC in a music metadata workshop, but today I actually listened to it on my tube ride into Central London and back. It kind of works. Then again, we did once play Blur’s ‘Parklife’ 21 times in a row on a student radio show I co-presented back in the 1990s, so maybe I’m unusually conditioned for musical repetitiveness!
