Windows 7: MusicMatch Jukebox for Windows 7

Where can I find a comparable program to MusicMatch Jukebox that is compatible to Windows 7. I'd gone to a sight which falsely advertied 100% compatible to Windows 7 and lo and behold, I get an error that a PX.DLL file is missing. There was a time when MusicMatch Jukebox was the greatest recording engine ever. Sadly, it was replaced with such a horrible piece of junk from Yahoo music. It would be nice to have software that will allow you to record music through the input jack and burn it to CD. I'd processed LPs and cassettes, 45 singles and even 8-tracks to CD with that software. Now, there is NOTHING that can do this.

Audacity is a free recording program that can export your recordings to WAV files, or even MP3s with a certain codec. I'm pretty sure you can record multiple tracks with it, but I haven't done that yet. It is compatible with windows 7 (even the version before the beta. I had problems with the beta, which they said was the only version supported under windows 7.)
Hope this helps!
