Well, so the ones on my old Minecraft songs post plus: trapped in Minecraft bybtryhardninja, all song by yourmcadmin, mine by Minecraft parody by dreamreaver23, locked in the Nether by dreamreaver23, I like my tnt by MC jams, Minecraft's end both Eric Fullerton (doesn't sound like a Minecraft song. But, it's parts of the end poem. Aka the long story once you go back to the overworld after defeating the dragon), I'm going hardcore by MC jams, let it blow deluxe by Abtmelody, my favorite things (Minecraft) By Pedro Esparza, I must build by Lindee Link,By pixel Sky block by devinepegasi, PvP by MC jams, glowstone love by Brad Knaulber and the ended men are teleporting by the glowstones. There are wayyyy more, but I only recommend these ones.
Not 100% sure if these recommendations are all 100% appropriate though. But, as far as I remember, none say any really bad words.
I know the one of first two (not sure which but probably the first one) and last one are in a few of the by by YourMCAdmin and the last one is probably in let it blow deluxe.
