I have been running OK until I added a few hundred tracks the other day. Now I am up to 4384 tracks and the whole app has crashed repeatedly. To wit, I open the app, select All Songs. One time it says zero, the next time it says 380, for example. Then via Menu I select Rescan. While the dial is spinning it reads 1000 songs, then 2000 songs, then 3000 songs, then 4000 songs, then 0 songs! Sometimes it will read 4384 songs, then change to 0 songs. The other main menu selections read a few low number of tracks. If I select Rock, it may say something like 135 songs. Well, I have probably 1800-2000 tracks of that genre! If I select Artists, it may say 0 artists, so I ask for a Rescan and it will create a list of artists with intiial letters from A to G, then skip to T through Z. My phone is an Samsung Droid Charge SCH-I510 running an Android version in the 2's, probably Froyo or Gingerbread. My SD card has about 20GB of music files & folders on it. My carrier is Vertizon. My Poweramp is "2.0.9-build-534 Full Version." The App has now become absolutely unusable. I am upgrading to a brand new Galaxy Note 3 tomorrow. I probably will not continue with PA. I do like the sound quality, but I have had nothing but problems with it, especially the management of playlists.
