I have my PSP mounted nicely on my car's dashboard (using velcro, works nicely) and use the PSP alot like a car head unit. That said, I've been searching and couldn't seem to find anything to replace Sony's default MP3 Audio Player, it's horrible. I was looking for maybe a homebrew app that can simply play MP3's, and maybe display some EQ effects? Is there something out there like this?
PS: If not, a "car friendly GUI"-MP3/Audio Player for the PSP wouldn't be such a bad idea homebrewers, you know, large scrolling fonts, "head unit"-like. ;)
