Pokemon HeartGold/SoulSilver, the 2010 DS remakes of the Game Boy games that added the train-as-you-move Pokewalker device, can now be relived sonically. The 270-song Pokemon HeartGold & Pokemon SoulSilver: Super Music Collection soundtrack is available for $9.99 on iTunes. Good thing you don't have to capture those tracks individually!
The new release follows the availability of soundtracks for PokemonFireRed/LeafGreen and Pokemon X/Y earlier this year. If you're still holding out for jams from other Pokeregions, remember that we can expect to seesoundtracksfor the following duos in 2014: Pokemon Ruby/Sapphire, Pokemon Diamond/Pearl, Pokemon Black/White and Pokemon Black 2/White 2.
If you don't already own HeartGold/SoulSilver but still want to kick up those childhood memories, this is a decent alternative from paying the steadily-increasing entry price for new copies of either game.
