My device-- HTC Hero (Sprint) running Android 2.1. I have two problems. One is music file organization, and the other is sound quality (of some very old lecture and debate recordings). FIRST----I need an app that will acknowledge the folders I put music in as "playlists" so that I can drag/drop the folders (playlists) into my SD card. The pre-installed music app on this phone isn't cutting it, I HATE the way it organizes files (it completely ignores the folders I create and reorganizes the music by composer/source/album/etc.). For example, I recently downloaded around 75 files (lectures) to listen to while I work (I am a grad student). I spent the time organizing them by my own categories in folders. The phone rearranged them completely and mixed them all up according to the way I described above, which drives me INSANE. They are still in their respective folders on the SD card, but they don't show up as "playlists" based on those folders. I want it to show me the music files basically as if I were browsing the SD card itself, in other words. This really gets crazy when you start adding in hundreds of songs amidst all the lectures. Maybe I am just missing something that's bluntly simple-- if you use this phone and can get the thing to recognize the folders as "playlists" then please tell me what I'm doing wrong. Second---- About two dozen of the lectures (some 2+ hours long) are very old recordings, originally done on 1960's and 1970's technology, and the guy speaking (Francis Schaeffer) has a VERY raspy voice. And thus the MP3 files, even on quality earbuds, sounds PAINFUL when you turn it up loud enough to understand him. At least the lectures were free. Are there any music playing apps that also have a graphic equalizer on it, such that I can fiddle around with the various bands to cut the harsh edge off of it?????? Most of the files are fine, but I've run into enough of them to justify looking for an app with an equalizer, but I don't know how to edit sound files in a legit editor, plus I don't know what files need editing until I'm listening to it, which is when I'm working. Thoughts? I don't mind using two different Apps for this if needed. Many thanks!
