Yeah, I found out DL#s definitely isn't an indication of quality!
Thanks for the tip on the comments. I've only just realised you can access a 'record' page for each track, as I was hitting the 'add' button previously. I'll be sure to check in there for feedback, cheers
One more question - I noticed a few tracks gave me 100% mastery even if I only hit a fraction of the notes. Is that a bug with some transcriptions? Also, some tracks seem to have pretty nasty 'leveling up', throwing me right in at the deep end on some, and on others, offering 1 note every 4 bars. Is that down to how the transcriber chose to have level progression for that track, or does rocksmith do it all on the fly?
