Somehow I changed the artist of one of my songs to O and now there are about 200 songs by this artist, how the heck can I start again.

If I understand correctly.. Edit the desired artist with the internal editor and push the "r" button on the right side of 'artistname'. Then type in the desired artistname. All songs associated with this artist will then get this new artistname..

If you find this a little counterintuitive Audiosoft just presented a much smarter layout for the internal editor, which will reach users before 4.0 is released..... Happy days

I found the ''update database'' button

Ah.. A very useful one indeed
