I have around 120 different MP#s with improper names
like 118_beam_vs_cyrus_feat_mc_hammer-u_cant_touch_this-usf.mp3
or Track 04.mp3
There are tools that extract the artist name, the song title from the ID3v2 tags and rename the MP3, getting rid of the underscores, numbers and other crappy signs
I could open the 120 MP3s individually and copy/paste the artist/song names but it would take too much time (and it's a real painn in the ass)
River Past Audio converter. Found a copy online last night with a crack and it works great for batch converting and getting encrypted audio files to MP3's
