Can Nero add Tracks?

I have a CDRW which already has some mp3s on but Nero doesn’t seem to notice???

I just want to add another track

Can Nero add tracks, or do I have to delete the whole CD and start over each time

If the disc was not burned in multisession, I think that it’s not possible to add further data.

Am i right to think that multi-session wont play on std CD players until they’re complete?

I just deleted and recut the whole disk - it doesn’t take so long, it’s just a shame for the sake of one track

I’m not sure, but probably a multisession disc will not play on a standalone even if it’s closed. If I’m not wrong, the player will be able to see only the first session.
