What My Cutie Mark is Telling Me (or WMCMITM, for short) is one of my favorite songs from Season 3. It was both fun and sad to see the mane six struggling with the feeling that they weren't doing the right thing.
Well, Golden Glissando did a super cool cover of WMCMITM in a jazz style. It's awesome! Give it a listen, I'm sure you'll like it.
Thanks, Golden Glissando!
