I don’t want something I have to deal with some software like iTunes for and would rather plug in the device into any computer and move files and have the player automatically recognize it.

Want to use it when going for runs. Audio jack and Bluetooth support is a must. No need for anything else fancy

Edit: I came across the SanDisk 16GB Clip Sport Plus MP3 Player. Seems like it might be what I’m looking for. Anyone have any other simple mp3 players with Bluetooth support they recommend?
