I have been a little too lazy to roder the DVDs by now. Unfortunately they switched publisher, so season 3 has no English (because of the different publisher). Season 4 has it again (after all the complaints, I guess). Last episode I have seen was episode 13 (though, I missed the first one). My progress is slow.
Songs I like the most are (in no particular order): Babs Seed (first song I ever heard), True, true Friend (song which made me want to listen to more songs), What my Cutie Makr is Telling me, This Day Aria, Hearts as Strong as Horses, Raise this Barn, Apples to the Core, In our Town, Winter Wrap Up and Helping Twilight Win the Crown. Pretty sure, I forgot some.
I think Rarity is quite amusing and intelligent too. I also like pinkie Pie with all her energy.
