Tough question. I'd have to say: - Flim Flam Brothers (from the show) - Party with Pinkie (Alex S.) Party with Pinkie just came out on top, in front of many other brilliant songs from bronies like Tombstone, Glaze, I could go on.
SCREW SMILE! BBBFF easily makes it to the top for me now. I think it's something to do with that I can relate to it; only replace the books with computers. I only started actually socialising with others around the age of 14, really. But I think it's also something to do with the whole fact that song's freakin' adorable.
In no particular order: This Day Aria(You can't beat that dramatic last 10 seconds) Winter Wrap-Up(Was like the first time I listened to Red Hot Chili Peppers) Love is in Bloom(Made me cry, so it's worthy) Smile, Smile, Smile(This song has been way overplayed by me, but I still like it)
Right, well, I guess it would be obvious what my favorite songs would be...sorry if I'm sounding a little...yeah. Here: [video=youtube;k10_b0Z5i5o]https://www.youtube.com/watch?v=k10_b0Z5i5o[/video]
