Use WinAmp or another media player on your PC to edit the ID3 tags of the songs. You can change the artist, song title, track #, album and year of the song. Edit the fields accordingly and they'll display neatly on your phone.
Here is another question then for you. I'm at work. I have a speak system that I plug my phone into to play my music. It's not connected to my computer. The cord that I have plugged from my phone to the speaker - could I plug that into my computer somewhere and use my Media Player to edit?
