Just tested it. The bug seems be gone in build-467. But after adding a new album to my default media folder, I opened Poweramp but couldn't find the newly added album listed in the "folders" section, and I had to go to Settings and Rescan to see the new album. Is it a way to auto detect newly added files when opening the player so that I don't need to rescan the folders whenever I add new songs? Btw, my phone is Motorola Defy with CM7 2.3.7 rom. I always add albums via USB connection. Last time I had this problem, the situation was: I was listening a song and wanted to played a newly added album, so I went to Folders - selected a song of the album, then it jumped to Player interface but instead of playing the new song I selected, it was still playing the old song. No error msg poped up, it just jumped to the Player interface and kept playing the old song.
