Playing music files from SD card

Alright, I have a question finally:

So I'm testing an Android 2.1 phone, and I decided that I wanted to put some audio files from my computer on there, and listen to them, since it has a 3.5mm audio jack. The radio works good, but choosing the music is soo much better. ANYWAYS:

I looked up where and how to add music files onto my microSD card, and I added about 20 songs. Unfortunately, I accidently unplugged it before I removed the device (stupid, right?) from the computer using the software. I plugged it back in, properly removed it, and started looking into the music player to find my files. Low and behold, there are over 2k plus 1-2 second audio files available to choose from. Of course there is no search function in the player from what I can gather, so scrolling is not an option (even though I tried).

So I did what any experienced IT trouble shooter does and Googled it. I found a possible solution, tried it. It didn't work. Tried it again, it still didn't work. I tried removing my music files from the card, and recopying back onto the phone. Still no luck. I'm at a stand-still because of my frustration. Anyone have any suggestions here?

I'd rather not mention the phone just yet, but it doesn't have Sense. I think it may be stock Android 2.1.

Yeah, I know how to transfer files onto my phone, I did it right every time but the first one cause I forgot one step. I mounted the drive each time. I added the files using the same method you described each time.

2k meant 2,000 music files on my phone, each of which is a second or two long, and are navigation directions. The files are for the navigation system, and have things like "turn left in 1/10th of a mile." The files are all .ogg format.

I don't want to delete those files, as the navigation system runs on it from what I can tell, and it isn't really my phone. I said in the first post that I retried copying and pasting the songs onto the SD card, but no luck.

That's worth checking out later tonight. Still searching for other ideas though. Also, has anyone else experienced the 2,000+ 1 second long songs in their music list like me? I know Fabien has, but I'm just curious if someone here has as well, and how they got around it.

Yeah, I'll look into reformatting it. I did look at DoubleTwist, but I don't use the iTunes store to buy songs, so...
