Control+Z and then "bg" should work (haven't tested it though)

Anyway I suggest you to use MPD instead

Regards

i like to use screen for this type of stuff:

screen -S myScreen

This will launch the screen program in your same terminal, using whatever label you want ( "myScreen" ). Then at the prompt, launch your app as normal, e.g.:

mp3blaster

then you can detech from the screen and return to your original terminal by pressing [CTRL]+[A], then [D]

To re-attach to it, run a command to list your currently running screens:

screen -ls

and look for the output that has your label in it ( "myScreen" ), it will look something like:

    10046.myScreen (Detached)

Then reattach to it like this:

screen -r 10046

Also, I've never used mp3blaster, but can you start it up in the background the old-school way, with an ampersand?

If you only use one screen you can use

screen -raAd

To reatach as well.

mp3blaster &

Will have the same problem as he already is having ;)
