They make you use that special SD card because you can't listen to that music on anything except your phone. You can't transfer the files to a computer or anywhere else. Plus the songs are in some super compressed format that only takes like 10 seconds to download a song so you can supposedly put like 3000 songs on there. That's probably the only way Cricket could make the deal with the record labels. I have a 16 GB class 10 card myself, and I would never downgrade to their crappy card with only 1 GB of useable storage. If you are rooted and do nandroid backups and backup apps with Titanium Backup, that 1 GB won't last long at all. That doesn't even count moving apps to SD, pictures, videos, etc. What a joke.
