Yes, CJ. I didn't know. Are you suggesting it shouldn't be spelled out, because all customers will already know everything? Use the term once, then use the initials. It isn't rocket science.

It all depends on how one buys music, doesn't it? I obviously don't shop for music online enough to know EP yet I have an extensive collection - old LPs and CDs (and cassettes and reel-to-reel . . . ). Digital picked up through Amazon, where I don't see EP because I buy digital versions of discs. And I'm never going to go shopping for music from Kanye West. The point is, be kind to your customers. Don't assume they know everything, so spell out or visually represent your offering so they know how many songs are available. Keep this in mind if you want to bring new customers to your site who haven't shopped this way much before.
