"blocks" refers to both a song composed by C418, and a music disc that plays the song when inserted in a jukebox. The music disc is obtained from creepers killed by skeletons.
Because TNT ignited by a flaming arrow attributes all resulting kills to the entity that fired the arrow, a skeleton igniting a TNT block due to holding a bow enchanted with Flame, or shooting through lava or fire, also causes any creepers killed in the explosion to drop a disc.[1][2]

Music disc "blocks" now uses the .ogg format. Before, "cat" and "13" were the only discs in the .ogg format; all the other discs were in the .mus format, which was decrypted by Minecraft on-the-fly.
With the introduction of jukebox song definition, music disc "blocks" now has an associated .json jukebox song definition under data/minecraft/jukebox_song
