This seems to depend on the amount of DLC I bought. The more DLC there is, the higher the likelihood of the game freezing. After the current Steam sale it's about 50-50 I can return to the song list without having to restart the game which makes it pretty much unusable.
While it might not be a common issue it's certainly not unique:

Do you have a similar result to what was described in the Steam thread when verifying your game files in Steam? What file is repaired when verifying your files if any?
