The Bryce Harper music download card (right).

The Nationals gave out Bryce Harper music download cards from T-Mobile to the first 20,000 fans at Wednesday’s game. What the heck is a Bryce Harper music download card? I was disappointed to learn it’s not something you use to download music that Harper composed while on the disabled list.

The back of the card includes a link to this Web site, where, after submitting your e-mail address and date of birth, you can use a reward code to download Harper’s “exclusive playlist” or five songs of your choice from the True Trax catalog of music.

Here’s Harper’s “game-changing” playlist. “Flower” by Moby, one of Harper’s walk-up songs, is not available for download.

The card includes five credits and most of the site’s “millions of tracks” are one credit, but friends could combine multiple cards to download the soundtrack from “Frozen” (11 credits), also known as Zach Walters’ “exclusive playlist.”

I love me some “Dark Horse,” but I opted against Harper’s game-changing playlist. Here’s what I’ve got so far:

Take On Me – A-ha
Bring it back, Nats.

Kyrie (Eleison) – Mark Schultz
In honor of Nate McLouth’s breakout game. You can only download the Mr. Mister version that McLouth uses as his walk-up song if you get the full album, so I settled for a cover.

Games Without Frontiers – Arcade Fire
Peter Gabriel’s classic was featured in the season one finale of “The Americans,” which I watched over the weekend. Can’t get it out of my head. Can’t get Gabriel’s version via True Trax.

Posse on Broadway – Sir Mix-a-Lot
Nick Johnson’s walk-up song — and an underrated one at that — for at least a couple of years.

I’ll e-mail the download code (and snail mail the card, if you’d like) to the person who offers the best suggestion for a fifth song that’s in the True Trax catalog.
