Currently using the Podcasts app. I've tried most of them but never really found a need to switch.

However one thing I have not found in a single player and would definitely pay for in a heartbeat is the ability to tag/mark/bookmark spots in a podcast so it's easy to come back to later. (I listen to alot of informational podcasts and would often times like to re-listen to bits/pieces again)

I like Kap, but at least on my system, any clip longer than 10 seconds strips any audio.

This definitely looks useful, but it's not working on my end and looks nothing like it does in their announcement http://jmp.sh/2NwDFWF

Same thing happens for me. The update wasn't even showing for me, I had to delete the Craft manager and re-download it just to get the update.
