For the life of me I couldn't get any of the players besides Doubletwist to play my m3u playlists! Doubletwist worked but it was just waaayyyy to slow. I come from the iPhone and iPod where it was super easy to get your music on your device. So with that said, and this may be knowledge that most of you already know, but Im gonna post it because it may help someone. I created a folder titled "Music" in the root section of the SD card. Opened up iTunes and found the playlist I wanted to have on my EVO. Right clicked on the playlist title (in itunes) and exported the playlist as an m3u file on my desktop. Opened the Music folder on my EVO and simply dragged and dropped the m3u file into the music folder. Then, I went back to iTunes, selected all the songs in that playlist, and dragged and dropped those songs into the Music folder on my EVO. Disconnected the EVO after the transfer was complete and fired up Btunes. BOOM! My playlist and all corresponding songs were there! I checked Doubletwist and the playlist showed there too! So I hooked the EVO back up and transferred a bunch more playlists (about 6 gigs worth) and Btunes and DoubleTwist showed those too! So right now, Btunes and DoubleTwist (the only two I tried) work with this method. While it may not keep track of playcounts and things like that, it does work for now. Hope this helps someone else! EDIT: 3 Cubed shows the playlists and the songs in the playlist but it won't play the songs.
