SongPro MP3 player for Game Boy
By bohus

I say "struggled" because the SongPro was originally called the SongBoy, and the original plan was to manufacture the carts outside of Nintendo - both acts inspiring a suit from Nintendo. After some bad press and Jesse Jackson being called in to mediate, SongPro finally hit shelves in 2000 with rap star Nelly contributing custom music on the included CD.
The $99 SongPro package was well thought out - the cart's form factor was more suited to the Game Boy Color (pictured here), but works on the GB Advance. It supports MP3, WMA, even a custom format displaying pictures with music - all using standard SD memory cards. The company even worked on pie-in-the-sky ideas like in-store kiosks for music purchase, and an online music store.
I admire the tenacity of the inventor, and many of his proposed ideas are important parts of current services like iTunes. I don't see a product like this being too interesting today as a Game Boy isn't the pocket sized device that today's MP3 listeners demand. On the other hand the old Game Boy offers a nice big screen for arranging your songs, and graphic control of EQ and other amenities, hence my using SongPro last week to play intermission tunes during a live music event.
Cool as these features might be then or now, it wasn't enough to make the SongPro that much of a success. The form factor of the cart was all wrong for the then newly released Game Boy Advance, and the combined cost of the game unit and the player was a bit expensive compared to MP3 players of the time.
Of course, I found my SongPro clearanced for $10, so needless to say I think that the price was exactly right.
