Hey - haven't been playing too long, but I like to supplement the Guitartricks lessons with learning songs. The selection here is great, but there are a lot of songs I'd like to learn not available (mostly heavy guitar rock - Sabbath, Zeppelin etc.). Anybody here use Ultimate Guitar Pro? I'm thinking of the subscription version, looks like it's about 30 bucks a year. Would be willing to pay that. I know that there is a free version, but it appears the premium version has an interface that I'd prefer.
