30 Song Mega Pack

This game along with the Rivals add-on is fantastic. Worth every penny.

All the songs in this pack are Harmonix-linked bands, either having friends of Harmonix or employees, or former employees, or something like that. A lot of them have been included in previous games as Bonus songs, but as of writing this review, a bunch of the legacy entitlements are still messed up for those. Not the most well-known songs, but I'd say at least half are worth your money, and at $15 for 30 songs.... might as well, I guess? Especially if you get some rewards credits or a gift card code, makes it even more cost-effective. (I understand the low scores due to the unknown nature of these songs, but there are definitely some gems in there)
