The music application that comes with my droid razr is ok but it seems to have a lot of problems with mixing up files and grouping songs under the wrong artist. Things like that. So, I decided to try out some other apps instead. I tried winamp first and was having a lot of trouble with the phone locking up. This happened especially when trying to view albums. I'm assuming it was having trouble populating all the album art or something. I uninstalled winamp and decided to install the trial version of poweramp. While it seems to be working a little better I've had it lock the phone up as well to where I have to do a restart. Any ideas why this is happening and any solutions?
