Yes, the mp3 is playing fine on my end, Funny I was working on that tune all morning even though I’ve played it so much over the years. So many ways to approach the great old standards. Interesting how you started it in 3:4 time and then a fast swing. Perhaps work on the swing feel. Sometimes it sounded like straight eighth notes and other times overly swung, if that makes sense? The song can be played straight ( usually as a Latin) or swung of couse. Thanks for sharing your work!
